| Subject: | Re: Low RPM on Takeoff??? |
Thanks for all the help so far...but no solution yet.
We have checked just about everything everybody suggests but no luck.
Went over the carbs with a magnifying glass - couldn't see any leaks. sprayed it
with hair spray just in case to try to seal anything micro small. We even took
out and inspected the diaphragms up close.
No obvious intermittent grounds. Engine runs fine most of the time. Mag check drops
about 50rpm both sides every time.
Burning through premium gas regularly and diligently checking for water now.
All the rubber connectors into and out of the carbs are in good shape without cracks.
Changed the oil, cleaned or replaced the filters (air, gas and oil) and lubed every
other moving part. Even changed to a brand new backup propeller we had and
carefully tourqued all the bolts in place.
We have marginally improved - WOT to about 5100 on first application and up to
about 5300 after the 800ft run before t/o. (As high as we want in the air).
Having a professional Rotax mechanic take a look but I will be very surprised if
he finds anything obvious after our detailed examinations.
Oh well - it still gets off the ground and pulls the plane along (Tecnam P96 Golf)
so we still fly! Just wondering where our previous get up and go went?
