mine today was turning 8650 in a few hundred feet, what's the recommended max for this engine?
Do not use the "Max RPM" reading on the dash. It can be inaccurate due to electrical interference. Use the analoge reading, although its a little harder to use while at full throttle. 8650 is way too high. Should be 8000 + or - 200.
