Greetings all, I need some advice regarding some issues I am having with my IO-360. This week I flew my 9A for the first time and while I do have that RV grin the grin is not as big as I was hoping for.
The biggest issue that is concerning me is the engine does not develop full power. On takeoff I get smoother performance if I pull the throttle back about an inch with no noticeable decrease in engine output. Today I was running full power at about 2500' full rich and the engine just didn't seem to be putting full power out and my RPM was about 2300, . As a test I leaned the mixture about an inch and all of the sudden I was getting 2500 rpm and the engine was running much better. Manifold pressure remained pretty constant and of course fuel flow went from 16 to just over 14 gph. That probably makes sense to somebody on this forum but it doesn't me....yet.
Does anybody have an idea and a suggestion for remedy? I did email Don from airflow performance since its one of his fuel servo's (EX-5) and I'm sure he will have some advice as well.
Thanks for any help!
