engine help!!!

[PAbobert]

I have a RC10 GT. The motor went in it and I replaced with an used one off ebay. The question I have is. I can get it to pull fuel up to the engine. The engine has decent compression, and if you blow lightly into the muffler hose the fuel goes right up. Does anyone have any ideas???? :( :mad: :(

If you crank the motor over while plugging the exhaust does it draw the fuel to the carb? (it's like blowing into the tube but not) this will tell you if the motor is putting the compression out the exhaust port. If it does then it could be the glow plug, or timing of the compression stroke is wrong. Is the motor wet meaning is the fuel is getting to it and going through it without burning, or dry. could be a carb issue if dry (plugged or air leak?). If fuel is running completely through the motor into the exhaust then it could be flooding or too cold a plug (or again timing) when the motor "went" what was it doing, how hot was it, and did you rebuild it afterwards? if you rebuilt it I would guess the lining is off and timing is now altered. but would need more info into what it did and what you did.
