Hey guys, I've got a briggs intek 17.5 hp engine on a Troy Bilt rider. I've had two batteries go bad on it. So, while testing the charging system, I found it to be charging, but it got to over 16 volts after cutting with it for awhile! It was around 16.5 or even a little higher! It's possible...

Not sure if ill be able to post a video or not. I may try a little later. Shop has been getting SLAMMED with work. Normal for July/August, but this year has been exceptional. Really sounds like there may be some kind of damage to the internals, I dunno, just sounds rough and unusual. Never heard...

That wasn't it :cry: May be a cam or something. This motor sounds ROUGH! Think I'm about done with this money pit. It needed a starter too. Kohler Courage are POS (n)

Thanks alot for that good info. That makes alot of sense. I don't have a timing light however, and decided to just go ahead and order the conversion kit. It should be here tomorrow. Maybe tomorrow or friday I can find time to install it and give an update. Thanks alot for the help

thanks alot for the info. Do you believe this would be cause for a motor skipping? Running rough? compression is good, new spark plugs. Both coils are firing, but just runs really poorly and doesn't sound carburetor related to me. You can pull the choke and it gets worse, letting me know it's...

Ok, thanks for the reply. It's a model # SV735-0016 and has the coils with lots of wires running to them. Three prongs on each coil and 2 wires running to each prong, for a total of 6 wires leading to each coil. I can try to get a picture tomorrow. I believe this is the setup that is on it...

Hey guys, Anyone put one of these conversion kits on before? I've got a mower in the shop that cranks good, has good compression, new spark plugs, but just runs ROUGH! Pulling the choke makes it worse, so don't think it's a clogged carb. Doesn't really sound like a carb problem anyway. More...

Hey guys, I've got a John Deere LA115 in the shop with a transmission oil leak. It appears it's leaking out of right side axle seal and possibly the input shaft seal on top. It's a tuff-torq transmission. I do notice a *slight* up/down play in the axle also. Very slight. There is an axle...

Hey guys, I'm looking for a tapered bearing for a tank M54 cub cadet. It's measuring approximately 1.245 id and 2.44 od. I believe the spindle part # is 918-05125, but it's around $265. Looking for just the bearings. The breakdowns I've found don't show just the bearings. Thanks

That was it. I guess this is a case of "couldn't see the forest for the trees" Although, in my defense, i did just drive the mower in the shop. So I was thinking it was something I did wrong in the installation. Just had some air in the system. Thanks

Hey guys, I just replaced the charge caps on hydrogear zt3100 transaxles. Something ive done 6 or 7 times over the past 2 or 3 years. Always goes smoothly. Takes about 30 minutes. The factory caps are known to leak and are replaced with an updated cap, part # 72274. All the ones I've replaced...

Hey Mark, thanks for sending that video. I didn't know about that! Good info. I did get clutch working another way, however. I was able to put jumper wires in the reverse switch and the RIO switch, effectively bypassing them. The clutch kicks on and works good now.

Hello, I've got a LA145 rider in the shop that has something weird going on with the electric pto clutch. It quit coming on, then I hit reverse and it started up! Strange. I thought it must be the switch connected to the drive that determines if the mower is moving forward or backward. (It has...

unplug one spark plug wire at a time while it's running (use insulated pliers or a screwdriver so you don't shock yourself) If one causes motor to shut off, then the other cylinder isn't running.

Hi Guys, A customer of mine asked me about the diodes on the kill wires of a JD 125 with kohler engine. He says they are located close to the coils on the motor, on the kill wires. One per coil right after the kill wire Y or fork. He says he bought a 10 pack of diodes off the internet and has...

Hey guys, I've got a motor in need of a cam. Pretty common cam part # 793880. Probably replaced 10 or 20 of them over the years. Currently the distributor I use is out of stock on this part. Found out they have aftermarket ones on ebay for around $30. Good price, I just wonder how good they...

I believe 7/16 wrench fits the plug. A 1/2 extension will fit over the plug and remove it. A little loose, yes. But it works good

Make sure valves aren't stuck open. That could make it appear that only one cam lobe is doing it's job. The push rods require the valve spring and rocker arm to return them back to the tappets.. if that makes sense

We've done alot of Kohler head gaskets. They have an updated head gasket P/N 32 841 02. I think they've known about this problem for awhile, but seems like they still put the weak head gaskets in from the factory??

yes, it's an aftermarket 491588. I've never had a aftermarket paper pleated air filter cause any restrictions, but anythings possible I suppose. Still haven't got back around to trying a new filter let. I'll keep yall posted

The carb that was on the mower was the stock oem carb. I ordered a carb online straight from Bangcock, lol. Both do the same thing. The old oem one acutally ran a little better, but both flood out when I put the new air filter on. I may try a different air filter just to eliminate that as a...

Hey IL, It has the auto-choke system. I've checked to make sure it's not stuck on choke. The choke is fully "off choke" so that's not what's causing it. I'm almost tempted to believe the new air filter is somehow not letting enough air through. Although that would be the first time I've ever...

Hello, I've got a briggs engine on a push mower that has me stumped. It wasn't running. First thing I found is the coil was spaced way too far from the flywheel. Reset the gap and the mower cranked up and ran good. Put the air filter base and filter on and it sounds like its flooding. Brand...

Ended up drilling a hole slightly smaller than 1/4" fuel line in the valve cover, crammed the hose in there, and is working nicely. Was a little nervous about drilling the cast aluminum valve cover, but it worked out fine. Thanks

Strange question, I know. But I have a new engine that came without the optional pulse fuel pump. It's a Loncin 17 hp, and I'm having a hard time sourcing the correct dipstick tube with the nipple made into it. (how the OEM Loncin motors come with the fuel pump) I could possibly drill a hole...

Hello everyone, Got a question I think I already know the answer to, but wanted a little verification. I've got a kohler command 25 vertical that is blowing a light mist of oil through the breather hose. Very light mist. Also has the hissing sound when you shut the engine off, the last few...

Hey guys, I own a small dealership for zero turn mowers, as well as blades, belts and other parts for many different mowers, and a repair shop. I was approached today by a salesman from Encore and he gave me a program and pricing on the mowers. The price looks good and so do the specs. I...

Thanks everyone for chiming in. Been a few days since I checked this thread. I think the novelty and history of the Vanguard is what drew me into the thought of giving it a shot. But until it is proven in the field, I believe i am going to pass on it and stick to tried and true FX Kawasaki...

lot of good thoughts. I appreciate the advice. I'm a little concerned also, the reason I started the thread. May not be worth the risk. I'm definitely not a fan of most Briggs engines. The cheaper versions are not good, IMO. I thought the Vanguard might be the Crème de la Crème. But don't want...

Hello, Curious about opinions on the new B&S Vanguard 40 HP EFI that's being put on commercial mowers. Vertical shaft I believe. I was always a fan of the older Vanguard engines. Someone said they used to be made by Datsun and were top of the line engines. Just wonder if it is still true about...

Hey guys, thanks so much for the advice. Very much appreciated. It turned out to be a simple problem. The tank was full of trash and there was no filter on the line. So trash was getting in the needle valve and preventing it from closing all the way. Doh! Should've known better. Thanks for the help

Hello, I have a kohler command single in the shop. I think around 17-18 HP. (model # is worn off) It has a mechanical fuel pump mounted to the side of the block, and has a problem with leaking gas into the cylinder. Weve tried two different carburetors. Rebuilt with new needle valve and...

Yes, it would seem you are right. But...I can touch the solenoid with a small guage wire connected to the positive post of the battery and it cranks very easily. Which tells me the battery, solenoid, starter, and ground are all good. It does get 12v to the solenoid when I turn the key also. A...

Thanks for the reply. The solenoid is made onto the starter and the entire starter is grounded directly to the battery with a big wire, 4 guage or whatever is used on mowers. Also have replaced the solenoid with the same problem. I believe the solenoid grounds through the starter when you bolt...

Thanks again for the help everyone. We never could figure out the problem, although it did seem to get better about cranking with the key. The battery seemed to have plenty of voltage and amperage, because you could jump the solenoid and it would spin and crank very easily. Just when you tried...

Yes, that's the part # i came up with as well, and the one I ordered. Funny thing, we've done one of these same units before and had the same problem. But the guy who finally figured it out is no longer here. He added a wire to it I believe. Wiring is not my forte. Especially with these mowers...

Hello everyone, I have an Exmark Turf Tracer TTX691KAE (312603620) in the shop that was having some wiring problems. The connector going to the motor was dry rotted, and being this guy is a full blown commercial customer, we decided to replace the wiring harness. It has seen lots of use and...

Awesome advice, thanks a lot for the help! Unfortunately we are still wrestling this bear. I made a light tester like you mentioned. But the bulb seems to be just as bright when testing it on the solenoid wire as when connected directly to the battery. Either way, its a good idea and one ill...

Just tried that. Still just clicks. I'm thinking a weak connection somewhere in + side of wiring. Gotta love wiring problems lol

Thanks everybody for the replies. Haven't had a chance to check it for last couple of days. I just performed this test, and sure enough it goes from 12.5 V to 6 V when I turn the key. So the issue must be in the wiring from the key switch to the solenoid. Bad thing is, it travels through a PTO...

It seems like it HAS to be a lack of amps reaching the solenoid, although this is a new one on me. It has enough amps to make a very audible "click" I can touch the solenoid and feel something moving in there. "Click" "Click" "Click" a hundred times in a row if you feel like clicking away. Click...

I know bad grounds can often be the source of the problem. Been through that a few times. This "seems" to be something else though. I've already removed the frame ground and reattached it, and the battery post and terminals look brand new. It has the automotive style round lugs and everything is...

I believe that's what its called. Its one that's made onto the starter that also pushes the gear up

Hello everyone, Long time small engine mechanic, having a hair pulling issue with a lawn mower in the shop. It's a dixie chopper silver eagle with a 27 HP kawasaki engine. I'm getting a signal to the starter when I turn the key, but all it does is "click" "click". OK, simple, its the starter...

Good explanation, thank you!

Hello, I've been wondering for awhile now what is the difference in raw edge and covered belts? Of course I know the obvious, that one is covered in some sort of clothlike material and the other is not. But what are the differences in performance, longevity, etc. I just don't understand why some...

It WAS the coils. Put the correct part # coil on and it runs good and has power now. Thanks for the help

ok, thanks for the info. The coils I took off must've been on there awhile. plenty of rust and looked original? Strange to have two bad coils at one time though? although this mower has been sitting for awhile. What coil should be on the CV740? If this is in fact a CV740. Like I said, the...

Ok, here's the info. The motor I'm working on must've had the shroud replaced or something, its got a blank sticker over the model that has #CV740-0036 wrote in permanent marker. The bad coils that came off the motor have part # 24-585-45 on both of them. I didn't write down the # of the coils I...

It probably serves both purposes, but itn does indeed prevent shutdown backfiring. A common problem on motors before fuel solenoids. Fuel would spray into the hot exhaust and "backfire"
