Actually........ no.
It would be a pointless exercise. If you're working with a chinagirl engine, the carb size isn't limiting your horsepower. It's volumetric efficiency is bad, being piston ported it can only make good hp in a certain rev range, and getting that output is more a problem of exhaust system volume and length, port timing, intake tract length and size, compression, cylinder scavenging and ignition curves.
Spend 500 on one of those high output 50cc 2 strokes over at DAX.
High revving power right out of the box. About 9 hp, I believe, 11 or 12,000 RPM. It comes with what looks like a simple NT carb on it.
See my point?
