With enough power, you can make a barn door fly---but why would you want to do that? Is there something wrong with the carb?
Is it the same size? Other wise you'll lose power.
Then you'll have to find jetting that works. Better to get it jetted right.
That thing pulls down and it revs. No need for anything else.
