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.

Regards,
CEN Racing
