Hello all, I'm trying to fix up a Chipper/Shredder where the compression is very low (35 psi). Tecumseh H35-45696S I lapped the valves and shaved off a little from the exhaust valve to get the proper valve clearance. Still low compression. I put some engine oil down the spark plug hole to...

I picked up a nice Troybilt pushmower with a 7.75ftlb Professional B&S Engine on it. Model: 11P902-0693-B1 The carburetor was heavily gunked up so I replaced it. Went to see if it would start up and...no resistance. Turns way too easily. Checked the compression - 0 psi I opened up the OHV Valve...

I'm trying to fix up this UT20818 Homelite Zip Start String Trimmer for someone. I cleaned up the carburetor (had some gunk in the screen filter), put in a new spark plug (owner didn't know where the spark plug was) and tried to start it up. I wasn't getting any spark though (It has a good...

Hello all, Decided to try some more work on some lawnmowers. I got one from a guy and it was in rough shape. Troybilt 12AV834Q711 I was able to get it to startup, but it makes this tapping noise while running. Is this the valves knocking? I set the valve lash to specs and didn't really notice...

I don't know if you all also follow this guys videos on youtube - I find most of them quite informative actually. Anyways, Project Farm just put out a video of efficiency and comparison of carbon deposits of Ethanol vs. Non-Ethanol fuel. I thought you guys might find it interesting enough...

Hello, I came by a 2014 Toro Recycler with a 7.25 B&S Engine (128M02-0133-F1) on it that wasn't working. The condition looked pretty good, figured it would be easy to get running. I cleaned the carburetor, replaced spark plug and air filter. Doesn't start still even with some carb cleaner...

So I've got a Yardman 11A-54MB055 pushmower in a pile of non-working mowers that a guy was hoarding in his backyard. Lots of crud all over it, left out behind his shed. Apparently it's a MTD 1P65 engine - looks a whole lot like a Kohler Engine on my Lawnboy. I cleaned it all up of the crud...

I understand that ethanol fuel is pretty terrible for small engines and ethanol free fuel is the way to go, but for me I don't think there's any gas stations nearby selling ethanol-free fuel since I live in Northern VA outside of DC. When I go to the box stores they sell the TruFuel 4cycle...

Hello all, Just wondering what are some good/popular service manuals (or textbooks?) to purchase for small engine repair? Mostly focusing on ones found on walk-behind mowers (B&S, Honda, Kohler, Tecumseh). Any ones that really stand out (Haynes/Chilton?) Thanks

Hello all, I took in a guy's lawnmower to try to get it running. It's a Troy-Bilt mower with a 6.75 B&S engine. Model: 126T02-0675-B2 The guy said he tried to follow a video about taking apart the carburetor so that he could get it running. But then he couldn't figure out how to get it all...

Hello all, I'm still new the forum. Trying to learn what I can from all you experience folks here. What are some good youtube channels to check out that teach about small engine repair (particularly lawnmowers)? Right now I've been watching: donyboy73 4DIYers fnaguitarplayer9 What are some...

Hello all, I don't have much experience with lawnmowers outside of simple push lawnmowers cutting smaller lawns in the suburbs. Lately I've been trying out picking up lawnmowers people get rid of, fixing them up and re-selling. One lawnmower a lady put curbside was a Craftsman 917.377792, which...

Hello all, I bought a few rundown mowers from some lady for $100. One of the mowers that came in the bunch was a Honda HRR2162SDA. She didn't seem to take care of any of the mowers, but I'm trying to fix them up. The Honda mower didn't run but I got it running with a new carburetor. Only...

Hello all, I had purchased an Briggs and Stratton lawnmower that some guy couldn't start for $40. Assumed it would be an easy enough fix. Model: 917.378451 Engine: 123K02-0183-E1 I got a kit to rebuild the carb and then replaced the spark plug. Figured that should get it going. But there...
