problem

I pulled the MX off the shelf to start reassembling the frame: the zerk fittings almost look like they arent even threaded??? Or if they are its a fine thread and they got trashed upon removal. I only have one original, I'm pretty sure the one on the headtube got trashed when I pulled...

Calling all Saxonette owners. I was changing the transmission fluid in one of my Sachs engines the other day and noticed a metallic swirl. This is from a 47cc Saxonette on an Arctic Cat. I've been around these engines since the late 70's, with a 30 year break in between, but have never gotten...

I replaced the carb on my stock Dirt Bug. Now the governor won't let it run under half throttle unless I manually push the governor arm toward the chain. I would appreciate suggestions for fixing this problem. L

I just recently put on a GTC Tav on my warrior and decided to put on a header, k&n filter and re-jet the carb with a .037 jet. The warrior then ran like poo with no power. I switched to a .036 jet and same thing. I've read other posts where the emulsion tube was replaced along with a new jet. Do...

I have a small B&S engine on a lawn edger. When installed on the engine, the recoil sometimes recoils, but most of the time it doesn't. When the recoil is not installed, it will always recoil. So I'm guessing its not the recoil spring. Any ideas and/or what I do to fix this ? This is a...

Ok so here is the rundown I recently took them off my doodle bug then accidentally pulled the brake lever and the pads came close together and were hard to separate so I took em apart and used a c clamp to compress the piston back in, last night I reinstalled them and they didn't have too much...

I've been working on this motor for my friend for some time now. He brings me parts and so on. The motor is around a year old and never had problems starting until I started modding the motor. First I did the usual air filter, header, valve springs, gov. removal. The engine still ran fine but...
