I have a mid-2000s TGB Laser R5 49cc 2stroke (belt drive I believe) that needs a new carburetor. The old one was a Mikuni that was in bad condition. I ordered one but the air filter mount was way to big. My air filter mount is about 30mm, with about a 22mm intake. Anyone know where to find one that fits what I need. I don't know much about engine terminology so don't go all techie on me. Thanks, Daniel
