I’m hoping to get a little advice. I just put a 35mm PWK air striker carb on today. It came new from Sudco with a 160 main and 48 pilot, dek needle. It was extremely rich on low end. I’ve gone to a 45 then a 42. It still has a slight stutter off idle and seems to be smoking more than usual in the idle to 1/4 throttle range. Not getting very much feedback from the air screw either. The stock pj was jetted at 160 main 45 pilot and was pretty good. Engine is tight with no leaks, compression right under 200 psi, stock pipe, rad valve, fmf silencer, vented airbox lid. Mixing VP110 and non ethanol pump gas @ 101 octane, 32:1 927. Elevation @ 275. Below 42 pilot seems small to me. Is it possible that the factory 4.5 throttle valve is too rich? I currently have it jetted with a 40 pilot, 162 main, needle clip in 3rd, and as @ 1-3/4. It still has a stutter off of idle. Any help would be greatly appreciated.
