Ok bear with me guys please, I'm trying to figure it out and expand my knowledge of these engines..
It seemed to go back and fourth pretty smoothly without a glow plug, but it has a big flywheel on. I took the whole motor apart (drilled out head bolts) and the piston does not go through the sleeve easily at all, in fact by hand I had a hard time pushing it through completely.
I heated the brass sleeve up to maybe mid 100s, and it was still pretty tight going through. The piston, sleeve, and button look pretty good, in fact like it hasn't been ran much at all, the rest of the engine is pretty clean.
From what I've read, bad pinch is when you can push it through easy, which is different than what I am seeing?
Also, when trying to start it up, it was vaporizing fuel out of the carb.. spraying it out in fine mist
sometimes I want to say it may have tried to ignite and spin the other way (jerked off the started box as I was holding it)
Anyone got any clues? I really don't want to just give up and would like to figure it out and become knowledgable. I want to say it might have been rich but I tried leaning out and it still wouldn't start.. it should at least start, right?
also if it makes any difference, fuel would flow back to the tank from the carb right away, it would not "hold" in the fuel tubing like my other nitros, as soon as I stopped trying to start it, fuel goes right back in.
I appreciate anyone willing to give some pointers
