I have a Fox 3.2 First used engine I ever bought. It had a bad rod bearing when I got it. I'm going to replace the top rod bearing soon. It's making noise.

But, it runs great. One of the guys at the field today said it was the smoothest running gas engine he'd ever seen. It's on a GP 1/3 Pitts, and the tail doesn't even quiver when the engine is running. You could set a BB on the tail when this engine is running, and the BB wouldn't vibrate off.

I'm around 4500' elevation--maybe 4800'. The engine has a C&H ignition and I have the timing completely retarded as far as it will go. It is turning an NX 21-8 at 7200-7300RPM. I bet it would turn a 22-8 at those RPM if I'd get out the degree wheel and actually set the timing at 28* BTDC. As I said, I have it set completely retarded right now. Don't have a clue where it's actually timed, but I'd bet money that it's nowhere near 28* right now. Probably more like 20* or 24*

Smooth runner. Choke it untill it pops and then flip about 5 times to start. Putter Putter Putter

I don't care what it looks like. It's buried under the cowl.
