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...

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

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

Hello all, I have a 25 HP Kohler Command CV730 in the shop. I've been through the carb, replaced fuel lines and filter, fuel pump, spark plugs, tested compression (135 on each cylinder) Set RPM's at 3400. It cranks and runs really good until you put a load on the motor. Then it is very weak...
