My hangar mate has this nagging RPM issue. We would appreciate any suggestions on how best to troubleshoot and fix.
The plane is an RV-8, 0360, Constant Speed.
The problem: During the first takeoff of the day, max rpm of 2700 can be reached.
On a few occasions RPM has surged to 2800 on takeoff.
On subsequent takeoffs you won't see any more than 2400 max RPM.
This problem has persisted across and engine removal/rebuild, a new Hartzell BA prop and a new governor. The A&P/AI on the field has looked at it a few times and we are all stumped. Tach (mechanical) has also been checked.
Could this be linkage related?
How would you troubleshoot this problem?
Suggestions appreciated.
Mike
