but wait.. the wiki says:
"8. Tuning/Timing: Slow down or retard the point of ignition by 1.8 mm to 2mm before top dead center. Change the spark plug for a grade equivalent to B7H. "

Where did you read the timing was supposed to be advanced? Really curious as I don't think the timing on my metra65 is quite right yet. I'm about at stock timing right now but haven't wanted to advance past that because of heat issues and the fact that the directions i read said to retard the timing, not advance it. Then again it's just a moped so i guess i'll just fuck with it and see what happens.
