- there is no idle air/fuel mixture screw
- pilot is a 37 / main is a 102
Since I had my old stock PZ30 from the Brozz, i decided to use it instead. I used 2 shim washers under the needle, kept the 37 pilot (Brozz was a 34) and changed the main to a 110. Turned the a/f out 2.5 turns.
Started right up and a short ride reveals it to be much snappier and no deceleration popping!

Really excited to hear your experience in the carb tuning area. You mentioned there is no air/fuel mixture screw and then mentioned turning a/f out 2.5 turns. What are you turning 2.5 turns? Or just a keyboard mistake? Thanks
