[catscratch1]

OK Guys heres the question: When the outside temperature is cool (17C)and the air has a high moisture content should you richen the high speed needle or should you lean the high speed needle to get the best performance from the motor? Your help on this topic would be helpful THANKS RON

That's 62F, so lean it a little. Run the engine about 82-93C. It should perform good at that temp and be safe. Listen to the engine and watch the smoke trail, always tune for good smoke and performance before worrying about temps. i only pull out the temp gun after I am happy with the way it's running.

93C is right around 200 degrees F, a little too cool for a nitro engine. Try more like 105-110C. Right around 220 degrees F.
