a 61fx thing
Baxter,, my 61FX is ether on it's 7th or 8th gallon, it runs and starts great with a Slimline Pitts, and the Compression is very good,,, but there are 2 things I got to ask about,,
A) as I'm tuning the High Needle to find the Peak RPM (at full throttle) there is a good 1/3 of a turn where there is no change in RPM, this happens right at Peak RPM,,
another way to put this is as I'm leaning the High Needle (at full throttle) as soon as the Engine reaches it's Peak RPM I can turn the High Needle another 1/3 turn more before the RPM's drop from being to lean,, is this normal ??..
B) I'm finding from week to week, every Saturday I need to lean the Low Needle, I don't think the Low Needle is moving in flight,, could this just be because the Engine is getting more and more time on it, or is there something else that can cause this ??
if there is anything you need to ask me about this please do..
