Welcome to the forum!
Ah, modern fuels and old fidgety carburetors.
Can you clean the carburetor? They tend to get clogged from dirty fuel or from sitting a long time with fuel in them. Or it could be a corroded mess from being stored outside etc, etc.
Anyway, yes. There's better carburetors out there and sometimes they're better just because they're new. What are your aims for replacing it? Just want to ride or you're thinking you can sort of hot rod the thing with a new carb?
