Carb size increase?

[CaptonZap]

I just got a Sento 50 that was stolen and trashed, and I'm trying to rehabilitate the poor thing.
The carb is an eighteen mm size, and the manifold has the same size opening to the head. Can I buy a larger size carb and manifold and install them, and have any hope that it might improve performance?
I have a Shanghai Meitian 50 cc that has a 24 mm carb on it, and it seems to work well.
Thanks for any input,    CZ

Yes you can a 18mm manifold will hold up to a 20 mm carb I have one on my montofino scoot gives it faster take off and the top end gets there faster. you will love it. you can even put in a bigger jet and open air filter in it and watch the looks you get from people you pass.

If you add a larger carb you will need to open up the Airbox ( drill holes ) to let it breathe better and get full use of the larger capacity fuel charge being brought into the motor from a larger carb....but its all for not..... unless you open up the exhaust as well to let the motor breathe better, which would require a free flowing exhaust...aka new pipe....then it will rock !
