Modern Vespa

I have Malossi cases, 60mm crank, BGM Big Box, and a Malossi top end, P200 motor. I currently have a 24.24 carb, I am putting a 28mm Malossi intake and 28mm PHBH. Maintaining the rotary intake.

Anyone have a similar set-up and have some ballpark jetting advice?

Thanks

I'd aim for the following:

Pilot 55
Needle x13
Atomiser AS264
Main 128
Fuel screw 1.5-2.5 turns out (most likely 1.5 turns)
No air filter, used bellow.

Had exactly the same setup as yours, sea level, 20-30c air temp.

One thing to note, rotary spit back because of scratches will be your biggest enemy. Any bad scratches and your idle will suck badly.

Thank you, that gives me a place to start.

Oh needle clip, second from top.

You might go to top clip, but only if you live somewhere like the Alps.

I am in St. Louis, MO, 466 ft above sea level so probably similar to yours.
