Was it "carb cleaner" or engine degreaser? This has me curious. Maybe a bunch of debris is inside the main engine electrical connector? Carburetor choke is stuck?

That takes too much time.... I'm late for something I don't have to do. LOL

Were the drive keys (Part #3 in the diagram put back in place? https://www.partstree.com/models/hrx217-k6-vka-mama-honda-21-walk-behind-mower-made-in-usa-sn-mama-1000001-mama-9999999/rear-wheel-19/

Sounds to me like you found and corrected the alignment problem. Never heard them called a "gemini drive".

Sorry, these .010 or even the .020 pistons are nowhere to be found. You are at maximum tolerance for the bore, I suggest you put a standard piston and rings to keep this going for a few more seasons. Most connecting rods like this get broken when the engine has been started cold and...

When all the vital information is missing, all we have left are little clues to eventually figure out some of the puzzle shown. Maybe we can come close to some of the models sold here in the US that are identical. Bolens and Huskee riders have a lot of the same features. MTD is a worldwide...

Sorry a centrifugal clutch was never designed for this application, then engine does not run at high enough RPM quickly like a chainsaw. Give it a try and you will find out fairly quickly with any considerable working torque trying to chip. If the chipper unit has a heavy flywheel (besides the...

I say hone it very lightly, then re-ring it and run it. Boring to oversize is impractical and very expensive to do in a machine shop and have them do it correctly. Conventional honing with a straight sleeve hone and drill just does not work with any accuracy to maintain a true, straight bore...

StarTech, gave a good link that should help. The label was likely removed to hide that the engine had been changed in the past. People do strange things so they can spin a sales pitch. In my opinion who really cares, it's not like it will be a collector's item someday. The mower "collectors'...

Look for a Julian day and year date molded/embossed into the rear tires. Not all tires had that, but many did. Usually, they would show the day like 120, then the year 07. (120 07) That might give an idea of when it was manufactured. The tires are usually withing a year of build date unless...

Glad you have it resolved. If there are any signs of smoke, heavy chirping or excess noise shut it down any check the idler and tensioner pullies for being loose or wobbly. A little play is not uncommon, but a lot will cost you that new belt.

A pull behind leaf sweeper with a hopper works wonders. Deck blades spin to fast (even at low idle) to gently pick up fallen leaves.

I was going to mention using a die grinder with a burr bit to shape the hole accordingly. Apparently, the engineers had a hangover when they drew up the diagrams for the stamping dies. The assembly folks did not have enough care to mention the problem, just like the QC folks.

I think the wheel assembly has to be replaced. They do not show the bearing separate. https://www.jackssmallengines.com/jacks-parts-lookup/part/husqvarna/501067001

Yes, I am referring to the keyed ignition switch.

Hi Robert, When it shuts down have you checked for an overheating ignition switch? Is the backside of the switch accessible? What about the after-fire fuel solenoid on the bottom of the bowl getting too hot and failing? Be careful checking for any hot wires or the solenoid because they can...

Hello SamB, Nothing wrong with using a vacuum method to suction the majority of oil out through the dipstick tube. Even using the conventional drain on these engines will not empty all of the oil. (regardless of also tipping the engine as well). All sumps have what I call "resting areas" where...

Hello bradcash, Look for the correct model number on the label under the seat it usually starts with "96" Have you look closely at the main drive belt and pullies with the deck removed from the underside?

By design, engine running centrifugal force and a small spring retract the cam compression release mechanism.

Hi RevB, As the saying goes.... "Hope spring eternal". How do people learn to be self-sufficient if no one is willing to teach them? Yes, it can be a lesson in futility at times because some are impatient and searching for instant fixes, but if even one person learns, that is why we do this.

Ebay, sell as is used. Starter spins when tested.

Verify the tank strainer is not partially clogged, fairly common.

Hi StarTech, I had forgot the differences between coils because I rarely get anything with points anymore. Points ignition systems were just being phased out back when I was starting out many years ago. I had also certainly forgot about the flywheel magnet polarity and correct coil mounting...

Is the starter acting up when it is installed?

We need a picture of the flywheel for reference. There are different designs. What engine number is the flywheel on? If it is only for triggering the coil, I don't think pole direction is important. If it is the magnets attached to the underside inner portion of the flywheel then the poles...

Ebay has a good selection of marine fuse boxes

Hello MH, I do not know if they are still available, but I will do some checking around. Initially, they were simple metal templates held on with self-tapping screws, then Kohler came out with an updated fan shroud design that had nut plates, so the screws would not strip out the holes in the...

Sorry hlw49, that has been a misleading story/rumor passed around for years. I was at the local John Deere dealer in my area around the time these kits came out. They were a Kohler v-twin fan shroud inspection cover kit. They are inspection covers meant to only check for debris. To actually...

Thanks for the reply, sounds like some creative engineering for sure. I did a lot of crazy modification like that when I was younger and had more time to experiment. My younger brother and I were into "modifying" go kart engines for racing (in the mid 70's) before it ever became a sport. Garden...

Right stuff is a great sealer that is not too difficult to fight with later, the drawback is that it is expensive.

If it is a 2004 model, you are under the illusion that you are getting genuine OEM. (You are only paying dealer prices for a "best guess" wrong aftermarket part) Aside from that, all of the electrical components are supplied by aftermarket contracted vendors anyway. The "factory" is just the...

What prompted you to replace the switch to begin with? Aftermarket switches are a best guess. Did you get it from an actual Hustler dealer or an independent repair shop that only claims it is correct? Not all switches are pinned the same or correctly.

I like it when a DIY type uses clear bathtub silicone and then wonders why it still leaks. LOL

The 3 fuel lines should be connected as follows: The (clear) main fuel line with the filter (filter inside the fuel tank) goes to the bottom of the carburetor (or the elbow shaped nipple). The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short...

The more they add to the plumbing the easier it is to have problems.

This is shaping up to be a used engine refit with a larger crank diameter.

I agree with slomo, At the very most I will only use ultra gray very thinly on a good gasket to reseal a valve cover, but not just straight RTV by itself. It takes prying the covers off if you have to readjust valves later. The biggest problem with RTV is the people who apply too much of it...

Sorry to hear that. Failed piston rings are not very common on this design from what I have seen over the years. Hopefully the cylinders are not scored badly. There is a chance the heads have warped in the pushrod area near the cylinders. That was an issue on some due to repeated overheating...

Hello TLloyd, Let us know what engine model you are working on. Otherwise, it is all guesswork. Crystal ball is broken and my lucky socks have a hole in them. :) Briggs and Stratton? Numbers are stamped into a valve cover. Kohler? Usually have a product label on the engine fan cover...

Hello Loulek77, A safety switch acts immediately and not gradually. Your problem description favors debris that is starving the fuel going to the engine. The trick is finding where the problem is. The most likely location to start with is a fine screen filter attached to the fuel feed line...

Glad you resolved the issue. There is way too much experimental garbage being put on machines and even vehicles without proper stress testing to prove they are worthy. Companies are too quick to rush products to market, they always have been by the vast majority,

Hi NormanB, That is rational. Verify the actual pump pulse vacuum line is not loose, cracked or split. The extra fuel means more weight in the tank so the fuel will feed easier to the carburetor. When the fuel gets low, the pump has to work harder. If the vacuum pulse line is cracked or the...

Hello tkos115, Have the heads cleaned and checked for any cracks and then resurface them using a thick tempered glass table surface and 400 grit fine (body shop) sandpaper. Note: Do not trust any bench top to be a true surface. If it has the nylon gear cam design, replace it. The tappets...

Hello ACF, A little puff of smoke at throttle up is not a bad thing. It will likely clear up with more use. Using Marvel Mystery oil is a very slow way to break down sticky carbon on the piston rings and ring grooves. Your power will likely improve slightly as well. Yes, adjust the valves...

I don't recall B&S making an 11HP twin cylinder engine. I'm still wondering how a "16HP carburetor" was mounted to this. The original description is a little confusing. The number on the engine cover are likely not correct. AKA Frankenstein build.

This problem sounds like one or more of the belt guides have been bent out of place when the deck belt was removed and installed (common problem). The typical upright belt guide pins that are near the spindle pullies practically touch the pulley when installed correctly. There are also...

Most zero turn MTD decks with a center single front hanger rod should be adaptable. The Z-Force models have a double front hanger design, and it would take a total redesign to adapt. If you have the design skills, a torch and a MIG welder, most anything can be fabricated. The only hurdle would...

Thanks NormanB, That is the engine info, thanks for that, but Kubota does not build the engine. What about the product label mounted on the mower chassis? That is what is needed to look up the design layout of the chassis and fuel supply system.

Hi Norman B, Sorry for your loss. I am a Veteran, and it is always difficult. As for your mower problem, this is a classic sign of trash in the fuel tank getting sucked in until fuel is starved down. If you can run it with the choke for a little longer that is also a sign of fuel starvation...
