Hi everyone. I'm fixing up my old Puch with one of these newish Polini carbs. So, I haven't found much on the tuning spreadsheets.
Out of the box the carb comes with an 80 main jet and seems to run lean. I don't know the current idle jet, but I believe it is also lean. I have ordered a range of OKO idle and main jets.
1978 Maxi Luxe
Polini 43.5 mm cylinder from 2008ish. Stock head. NGK B6HS
Polini single Reed valve
MLM 19mm intake
Polini CP17.5mm carb
Uni filter hacked and strapped
Tecno Circuit Exhaust
-Any jetting experience with this carb? Planning to jump up to around 100 and work down.
-larger jets are in the mail, but I am wondering if the minimal filter and lack of airbox are a potential issue. I believe the airbox slows the acceleration in airflow to reduce a lean bog when opening the throttle.
I'm looking for acceleration and reliability over top end. My odometer reads 7,800 miles, I probably put on a few thousand ten years ago, but it has been sitting since.
I just rebuilt everything from the base gasket up. Any thoughts on when the bottom end will become trouble? 10,000 RPM? 10,000 miles?
I appreciate recommendations and will update as the build wraps up.
P.S. looking for moped people in Long Beach, CA
