I have a JD D140 mower that I put a new drive belt on last spring. As the mowing season was ending up for the fall it started to slip more often. I’m wondering if either the drive pulley on the engine or the driven pulley on the transmission are worn out. Is there a way to tell if that is...

I have a John Deere D140 with a 22 hp V Twin B&S. I just overhauled it, has 140 hours on it. Before overhauling it I had to prime it with gas to get it started, figured it was because of low vacuum. I started it yesterday for first time since the overhaul. Figured it was from setting for three...

I bought a gasket kit for a B&S 22 hp engine I need to overhaul. There are only two valve stem seals in the kit. I looked online and all I could find says there are only valve stem seals on the intake valves. Just checking if that's true? I have the heads removed and mostly cleaned up. I...

I replaced the drive belts on my MTD 13AN682G129 lawn tractor. I cut for about 45 minutes last night and everything worked great. Tonight I mowed my lawn and after about 45 minutes of mowing the mower wouldn't move. The belt would begin to smoke if I let the clutch/brake pedal out. I took...

I just finished overhauling the engine listed in the subject line. The only thing I haven't done yet is the carb, engine runs good at full throttle, but a little rough at idle. I know the bottom of the throttle shaft is oblong, but I haven't checked the hole in the carb to see if it's out worn...

I've been in the process of rebuilding my B&S 31C707-0154-E1. I can't remember and can't find where it goes. The part number for the wiring harness is #698329. The wire runs under the front of the engine block plugs into the solenoid on the bottom of the carb with a pigtail. One wire then...

I'm in the final stages of rebuilding the engine in my MTD model # 13AN682G129. I need to replace the double pulley due to the drive pulley being so worn out that the belt would slip most of the time on it last year unless I put it in high gear and got it moving first. They want ~$65 dollars...

I'm overhauling my B&S Intek 17.5 hp, 31C707 engine. About a year ago the two brass screws came out of the throttle plate and went through the engine. The piston has dimples all over it. I removed the rings today and the top ring was very hard to remove, in fact I broke it a couple of times. I...

I have a Briggs and Stratton 31C707-0154-E1 16.5 hp engine in my Yardman mower. It's been hard starting this year and I've adjusted the valves about every month. Sometimes it will start sometimes not. The battery is good in it, so when it doesn't start I use my truck to jump start it. It...
