Okay, So I'm about 98% done with the build I just need to wait for some loc-tite to cure and go to the hardware store to get some new bolts for the chain tensioner since I somehow snapped one but there's an issue I don't know if I should worry about.
The engine head when it runs for a few minutes tends to give off smoke, I know it's not coming from the exhaust and there's nothing flammable like wires or cables touching it so I can't figure out what it is. The smoke has a interesting smell as if it was burning plastic but theirs no plastic on the head, I've never noticed it on my first 2 stroke build but I did pull the head off and put JB-weld on the end of the studs. Some fuel leaked on it but I wiped it away but it's still smoking, is it burning off imperfections in the metal? Is my engine eating itself (it's not making any grinding or disturbing mechanical sounds) but I'm afraid I might fry the engine before I even get to break it in. I'm using a mixture of I believe 16:1.
I don't know if this is relevant but when I kill the engine via releasing the clutch at a dead stop and it stops small amounts of smoke comes through gaps in the carburetor where it links up to the engine, I don't know if this is just exhaust that didn't escape or a bad sign, I need help guys.
