Need help with a px with polini 177

anyone know the timing settings?or jetting?
i have a px 125 with a polini 177 kit,race crank and its been using a pm pipe

Hi chelski,
which carb are you using?

I have a similar config except for the pipe, in case you have a SI 24 a jetting to start from should be:
min 55/160, max 160-BE3-130, screw two turns out.

The timing is 18° with the strobo.


Ops, I can’t be of too much help then…

im using a 28mm phbh carb
