Manco Thunderbird

Hello, I have a manco thunderbird mini bike, it has a Tecumseh 3.5HP motor. and it has a governor on it, and its missing the entire throttle assembly...which is kinda hard to find, and i was wondering if anyone knows if theres a way of removing the governor (and yes, i know that that increases the risk of the motor blowing, but i know not to rev the hell out of these type of motors lol), or possibly (if jetted correctly) using a carb from a crf50 or 70 type of bike would work...
Any suggestions are greatly appreciated
Thanks

Yeah, i was looking at my crf50 carb where it bolts on, and it looks about the same size, i took the carb off the 3.5 and it is the most simple carb design ever lol. i dont think the governor could be replaced or removed, i think im going to try to find a carb that will fit....and just hopefully it will work with some tinkering around lol...

Yeah its almost like a butterfly choke design...just for a throttle...lol
and yes i agree with mini bikes, its always more fun to customize them your own way
