I recently put truggy tires on it. It was only shifting into 2nd occasionally. I put a larger spur gear on it. Wasn't shifting at all.
Glow plug died, I replaced. Went on to burn up 2 more plugs. I chalked this up to running too lean. The piston and button show imbeded bits of filament.
I went back to stock settings on carb and have adjusted every which way since. The engine will only start up at full throttle and will cut out as soon as I release throttle.
I have tried an extra shim. With and without, no change.
What can I do?
The glow plug filaments probably toasted your engine. Disassemble the engine and check for damage to cylinder/sleeve. Maybe you could get it pinched, but only if the piston/sleeve is not too bad. Rebuilding is an option, probably easier just to replace it.
