Any recomendations for carb setup for the PHB30 on this engine:

Polini 208

Scooter&Service top

Longstroke cranck

1800g fywheel

SIP Performance exhaust

PHB 30 (not reed) Malossi inlet

Engine runs well giving trotle, but gets to warm riding longer distance on slow trotle and overheat when I close the trotle and piston jams.

Thanks ! Have entered the data. Nice page, but ofcource no engine runs the same and there is no standard setup.

I run today on

PHB 30 with

main 142

AV262

X2 needle

clip on top

idel 55

and the bastard engine keeps going to hot and the sylinder starts to pinch.

Any with experience with the Worb5 Polossi. Does the modified Malossi piston in the Polini improve endurance?
