Somewhere your kill wire is being grounded. May be this manual will help. Not your unit but who knows. I’ll try to find a diagram for your unit. https://www.toro.com/getpub/13300

I would check the carb, sounds like a lean running condition, which clears when closing choke. This manual may be of some help. https://www.mymowerparts.com/pdf/Kohler-Service-and-Repair-Manuals/Kohler-Service-Repair-Manual-Command-CV17-CV18-CV20-CV22-CV25-CV22-CV23-CV26.pdf

To me it looks like part of the governor yoke, which has been flying around inside the crankcase for awhile. I would test to see if the governor is operating properly.

This is what I would recommend, others may disagree. I’m assuming it has electric start. 1. Check the oil, level and condition. If it is not black, proceed. If black, change using straight 30W. 2. Remove plugs and ground spark plug wires. 3. Remove and plug fuel line before the pump. If...

Star, I found that one also, but the OP has stated more than once he wants a fix-jet non adjustable carb.

Maybe this website will help you. https://www.mymowerparts.com/pdf/Tecumseh-Service-and-Repair-Manuals/TECUMSEH-CARBURETOR-TROUBLESHOOTING-AND-IDENTIFICATION-GUIDE.pdf

Good luck in your search. Finding the specific carb which uses a specific main jet is not easy. Just as your carb came from a mower, I’m willing to bet that the jet came from a blower. Probably a “fix it job” done by a “DIY GUY” from his “ I’ve got something that will work” scrap box. If you...

Now I’m totally confused as to what you are looking for. I identified the carb in your pictures. Are you trying to find a lawnmower carb which uses specific snowblower carb bowl nut?

Looks to me like a Tecumseh #640278, but I’m running into a memory problem. Looking at your pic I don’t think that that carb came on a snowblower engine, as it is most commonly used on mower engines. Are you sure that it is the original carb? Do you have any numbers off the engine ID tag?

Update, looks like next Tuesday we’ll get above freezing, 32 degrees, for the first time this year. Problem is we’ve had less than 3” of snow during this period. Need to go almost to the UP to find snowmobile trails open. Looking and hoping for a couple of good February storms here in God’s...

I taught my students to use very light lubricant to eliminate as much stone clogging as possible. The heavier the lub the more it will grab any particles, plus I over use my lube. This does get messy, as I do get it everywhere, but to me it’s worth a good job. Most people do not agree with me...

If you have a local machine shop or old fashion auto shop, you might want to see if they have a set of telescoping gages and a vernier you can borrow. Will make your job a lot easier. I like your choice of hones and would use mineral spirits as a lubricant. Remember you must measure at top...

Grit size will depend on condition of the cylinder and how much material you want to remove. Are you resizing the cylinder or just have a cylinder within specs and just trying to put a good crosshatch in it? This will dictate type of hone (rigid or flex) and grit size. Hone a closed 2-cycle...

We can only call them as we see them and then give our opinion based on our experience and knowledge. If you have been around this forum for any length of time you would know that the techs who have replied to this thread have thousands of hours working on equipment and know a little about what...

I’d really like to see the blade from that spindle. Willing to bet it is either nice and sharp or with a nice chunk out of it, plus probably bent.

First off, please don’t start two threads about the same problem. This only gets confusing and doesn’t help you with your problem. Second, who are you dealing with and where did you purchase it? Have you talked to a Big Box center, Husqvarna dealer, or Husqvarna directly? Looking at your...

Once again I agree with Bert. Couple of things to add. Curvature of the coil legs is very important, as this will determine strength of the flux lines, duration of buildup and timing. Second, not all coils use the same type of triggering systems, which also control timing. To anyone who...

At that temp I would make sure the fuel shutoff solenoid on the bottom of the carb is opening. An amount of water in to fuel would freeze the plunger, not allowing it to open.

There are a few different methods of electrical troubleshooting floating around this forum to help you. This is the one I use. Electrical problems can be very easy or very difficult, depending on four things. 1. How well you understand basic electricity. 2. What tools you have and know how to...

This may sound stupid, but did you use a new sump gasket? Should be part number 697110 and have a thickness of .015”. If you are using the old gasket, it may be compressed too thin causing the problem.

When you turn the key to “Start” do you hear the solenoid click? If not the solenoid may be good, as you are not getting current to the solenoid if no click. You will now need to check all connections and grounds, then go through the safety switches.

As Scrub said, if the engine timing is off causing a lean operating condition, it will definitely overheat and seize up. Ask anyone who has had an engine on their racing tractor or go-cart explode when they had the timing to far off under high RPMs. They start the engine with either, keep...

Most likely the numbers on the crank are casting numbers, so unless you have the casting codes they mean nothing. Are both the slots on the crank, for the timing gear the same? Do the timing gear align at the same point? Do you have a vernier caliper to measure the thrust surfaces to see if...

More questions than answers. Do you have a tachometer and VOM? Is this generator just 220-240 or do you have 120VAC outlets? Is this a constant throttle unit or one that idles down when no load is applied? Working on generators requires a knowledge of both how the engine works and how...

Are you sure the two crankshafts you tried have the same part number as the one you took out? They may look the same, but have different specs. Also, two different crankshafts were used on that engine, what is your code number?

Some dealers do and some don’t. You’ll have to ask the dealer in your area.

Disclaimer: I’ve been selling and servicing Toro’s for 40+ years, so I’m a little biased. I would highly recommend a Toro model 21563 over model 21389, mainly because I like the handle setup better. As a service tech I also feel that the Toro units are easier to service than the Honda. I...

According to the numbers you posted they both use the same flywheel. Seeing you have two different flywheels, have you checked to see if everything is exactly the same? Magnet location in relation to key slot.slot, Flywheel diameter, Magnet size, etc. As stated I think you’ve found your problem

First, the second number should be 123K02. Both engines use the same coil and flywheel. Coil number should be 590454. Have you removed and checked the flywheel key?

First thing you need to do is diagnose where the leak is. I’ve seen units where the happy home owner has been ready to throw in the towel before finding that the problem was something as simple as a loose coupler or bad hose. My suggestion is to clean everything to look like new. Pressure...

Personally I don’t think you will be able to find a better carb. Those carbs are about as simple as they come and with proper maintainance work well. Most common problem is where the carb mounts to the tank. Tanks like to warp, making it difficult to get a good seal for the carb to work...

If the flywheels are different, then the coils may be different??? How about posting all engine numbers from both units, so we can do some investigating deeper.

I’ve used Redsquare a few times over the year and found them to be extremely knowledgeable and helpful. This is especially true on the only Wheel Horse “Mules” as I call them.

Totally agree with Bert on this one. I‘ve also have a boxes of used coils and used carbs I’ve removed from junkers and install on my “poverty “ cases. If you have found that will mount with one screw, have the same timing, have the same spark length, have the same power and not change position...

When you say “works perfect”, does that mean problem solved?

I’d set the armature air gap to .008 and see if there is any change. Very seldom do magnets go bad. Finally, checking resistance on today’s coils is meaningless, as they contain Hall effect triggers which you need high tech equipment to check.

Sounds like you may have a bad ground. Please post all engine numbers. What did you set the point gap at?

This site might be the best place to get those parts. https://www.wheelhorseforum.com/

Here’s a copy of the parts manual for your unit. You will find the bearing I’m talking about here, page number 5. Also check the condition of the steering and vector gears. https://www.toro.com/getpub/4720

Have you replaced the lower steering shaft bearing? This manual will help you out. When you post back include the model and serial numbers from under the seat. https://www.toro.com/getpub/6933

Anyone else seen an increase in pop up ads at the bottom of the screen when trying to type in a reply? Started awhile back. When I am typing in a reply an ad will pop up covering 75% of the reply box. Just wondering.

Easiest way to answer that question is to put some fuel in it and try.

Post the model numbers from under the seat. Then we will know who manufactures that unit.

Never heard of being able to do this, but I also say never say never. Would I try, NO.

With proper maintenance you should easily be able to get ten years.

This is a steel deck push mower. They only have a 2 year warranty.

With some searching you can find a free manual online in pdf form.

We also use SimpleGreen at a 5/1 ratio.

High today 23. Forecast daytime temps for the next 10 days, anywhere from -1 to 25. Nighttime forecast lows ranging from -11 to 18. Problem is that there is no snow in the forecast.

Never had a problem with the tank not being high enough on those old mules. Are you sure that you did not pinch the fuel line when you routed it behind the flywheel? Also, if you used fuel line which has a wall thickness which is too large. This will cause the line to pinch together when...

As soon as the engine starts to sputter disconnect the fuel line from the carb and check the fuel flow. We need to know if the problem is inside or outside the carb. If the the flow is good the problem is in the carb. If the flow is reduced problem outside the carb. You can also check the...

You definitely don’t want to come to God’s country. Forecast says we wouldn’t be above freezing for the next week. Forecasting -5 to -10 for the next two days, then heat wave Saturday at 28. Hoping for a few inches of snow to make the trails smoother and be able to get out to do some ice...

Also, check for garbage in the tank, causing the fuel to stop flowing.

Another thing to try is readjusting the governor. If it is out of adjustment it will cause surging. This manual may be of some help. https://www.mymowerparts.com/pdf/Tecumseh-Service-and-Repair-Manuals/TECUMSEH-SERVICE--REPAIR-MANUAL-3HP-TO-11HP-4-CYCLE-L-HEAD-FLAT-HEAD-ENGINES-692509.pdf

Also, going to need serial number.

Please post the engine spec number, as their are a 11 different carbs for that engine. This could be why you got the wrong kit. Also post the part number for the carb kit you purchased.

I’ve been working for Toro dealerships since 1981 and the pictures are different, but how to remove the bearing hoc is the same. My memory is not as good as it used to be, but I think I’ve done this repair a couple of times in the last 40 years. Since you know more than I do, I’m not going to...

I’m assuming you didn’t look at the manual I posted. Pages 4-3 to 4-7 have illustrations and steps on how to disassemble the hoc from the pivot arm. Also, your model number is 20340 and the serial number shows it is either 2015 or 2016, well out of warranty.

The part you show is called the pivot arm and the part you are trying to remove is called the bearing hoc. There should be a retaining ring which hold the two together. The shiny part is the bearing. Section 4 of this manual should help you out. https://www.toro.com/getpub/22446. I doubt...

I wouldn’t recommend trying to jump a Li-ion battery with a lead acid battery. Just my opinion.

I agree. Suggestion if you can, load the mower into your vehicle and go to your dealership. Ask them if they would install, or if you can, a new battery to see if our diagnosis is correct. That way you shouldn’t have to buy a new battery if we are wrong.

Very seldom have I seen the breather go bad. I would check for a blown head gasket before ordering a new one.

Measure the battery voltage when the key is turned to the start position. If it is less than 10 DCV time for a new battery.

This manual might be of some help. http://www.kohlerengines.com/engines/onlinecatalog/pdf/sm_14_690_01.pdf

Also make sure that your battery and starter cable connections are clean and tight. Particularly the ground to chassis connection, which is one that likes to come loose and corrode, causing a lose of current available to the starter.

Sorry, but I don’t know how if I’ll be able to help you more?? Having a knockoff carb, which probably not the correct one for that engine, is probably the main cause of your problem. My memory is not the greatest, but I don’t think I’ve ever seen the type of carb you describe on a Tecumseh...

The float may look fine, but it is the float level which you must check. It must be level from the pin side across or slightly lower on the side opposite the pin. This is with the carb held upside down.

Two things most often cause surging on those Tecumseh engines, Most common cause is that the float needle seat has swelled, due to sitting with old fuel, which now is allowing the needle to shut off prematurely. This results in a lean running condition and can be repaired by replacing with a...
