thanks again for the additional info...the reason I added the stabil to the auto
fuel is Lockwood emphasized adding a stabilizer when using auto gas in their
intro to rotax engines video. Is there a better stabilizer than the Stabil brand?
Also, another question for Roger...is it possible that if the intake valve
is sticking, could it cause "back pressure" to the carb causing fuel to back
up through the vent tube?..just a thought.Again today, after running the engine
(rough) for 3-4 minutes..moving throttle in and out some keeping rpm's between
2000 and 3000...it smoothed out and when temps came up to the normal range
a mag check was normal...power felt normal in take off, climb, cruise..only
had time for about 30 minutes of flight, but no problems and after shutting
down engine the compression felt very firm on all blades turning by hand...Again,
thanks to you all...I'll keep you informed as I work thru this, Paul P.
