RE: how to tune?
Here's how to tune a engine:
First start the engine up and run it around for about three minutes. Run it really hard like you're racing around a track. Then do a couple of full speed passes, after each pass lean the needle 1/8 of a turn each time. The car should get faster and faster on the top end. Eventually you will reach peak horsepower and after that each time that you need the motor, the power will decrease. At this point go back to the peak horsepower setting, and richen it a 1/4 to 1/2 of a turn past peak horsepower. Your car should have plenty of smoke this time coming out of the exhaust. Then bring the car in after a full speed pass and immediately let the motor idle while you pinch the fuel line anywhere. The engine should cut out after about four or five seconds. The engine should also rev up before it shuts down. If your engine shuts down before four seconds or it doesn't rev up, then your engine is running too lean and I would richen it immediately anywhere from 1/8 to 1/4 of a turn. After you've tuned the low-end correctly, then you can adjust your idle speed. This should be adjusted so that the engine does not engage the clutch at idle.
I hope this helps,
