Jetting for 24 mil carb with Pinasco 177 kit

Schaltroller / Classic Motoscooters Vespa Largeframe

I've put a Pinasco 177 kit on and I'm trying to set the 24 mil carb up with a PM pipe. I haven't as yet drilled the air filter but I'm running a BE3 with a 114 main jet. Runs ok at low revs but is really sluggish if I open it past about 1/2 throttle - I guess the main jet is too large but I really don't know. Should I drill the air filter, if so what size jet should I go with and if I dont would going down to a 100 or 112 but leaving the BE3 e a better option?

Thanks

HI;

 

HAVE YOU ALLREADY SET THE IGNITION TIMING RIGHT?? 18 btdc ARE NEEDED:

 

 

 

YOUR ACTUAL  JETTINGS SHOULD RUN OK FOR THIS SET UP

ALSO DRILL THE 8MM HOLE IN THE AIRECLEANER!
