Got the crate back in the air yesterday after 2 and half month sleeping.
Old Franky 165 starts good and run smooth, but when going full power for take off i get a ticking sound like a lifter
on an old chevy 350 c.i.. When I level and bring power back, it goes away. If I set high R.P.M. in level flight, nice and smooth.
Lower r.p.m. again, nice and smooth. only when climbing with full power or on take off I get this sound. When under high m.p. or high demand.
Could this be the fuel pump? Stuck valve would give me rough engine wouldn't it ? Also noticed fuel pressure a bit lower. Used to be 4 1/2 to 5 lbs
It shows 3 but had the fuel press gauge redone with the two other indicators in that instrument. Pumping the wobble pump while flying does bring it up.
I had a similar fuel pump on a GM car a long time ago and before quitting it gave me a similar sound.
