I have a 2165 with 44s and I am working through the process of jetting and setting them up right. I am currently at 57 Idles, 160 Mains and 200 Aircorrections with F11 tubes.

Starts and idles fine
Run up throught he idle jets seems fine
Decelerate below 2500 rpm and it is fine
2500 rpm I get surging
Run through 2500 and it smooths out and feels strong
Decelerate on the mains and I get a slight popping
Seems to run out orf steam at higher than 4000 rpm.

I am almost there I think...

Suggestions?

Thanks in advance,

Mike
