Hi Guys,
I have an fg-90 in a Phonex Waco and I find the top cylinder gets super hot compared to the bottom cylinders, its to the point where I have to just about idle around the sky as the temps on the top cyl jump to 150 – 160deg not long being in the air. the bottom temps are much lower.
Is this a baffling issue? or the high temp is normal for this motor, I think it would keep climbing if I didn’t back off?
