I have check the glow plug and it good but it wont start. also i am getting some nitro fuel coming out of muffler when i pull start, i didnt floor the fuel. do you have any idea what the problem? is there anything else that i need to check with? sometime the pull start is hard to pull, even when i keep pump until the fuel reach the carb i stop pump. help please!

warm the engine up b4 you start it with a hair dryer make sure u have put plenty of heat into it

I just found out that the muffler is spiting the nitro fuel out. is that normal?

hey, i finally got it start but there still little probelm. the problem is when i start it, it spit little fuel out of muffler when i pull the throttle. also when i pull the throttle, it slow. and when i let it go the thorttle, the wheel spin like crazy. and when i fill up the nitro fuel, it ran out in maybe say 30 seconds. help please thanks.

CEN Drifter,

The fuel / oil coming out of your exhaust is normal. This is what happens when your engine is running rich. Not all of the oil is burnt up so it has to go somewhere. The reason why your car was difficult to start is because the engnie settings were a bit on the rich side. If you lean out the top end about 1/4 turn, your engine will start much easier and you will experience less oil coming out of the pipe. Thanks for your question and have a great day.

cen racer , 2 stroke engine typically waste [dont burn] 6.5% of fuel where as 4 strokes waste about 4% these figures do slightly vary from different engine Manu.F
so it ends up back out your exhaust.
