ok i bought this bike for 150 with everything attached. the guy told me that the carb wouldn't quit flooding. i priced parts for the float ad the pin that goes with it. well i wasn't sure that would fix the problem so i purchased a new carb (a mikuni 20mm round slide) . well i got it in and it was a flange style instead of a spigot style. so i fabricated an adapter. the dimensions are about a 64th of a inch off but really close. i replaced the fuel filter cleaned the tank and put new fuel lines and a spark plug. second kick off it cranked up and idled Perfect. as soon as i give it gas it backfires in the carb or just peters out. i adjusted the fuel pin and it seemed to do better a little richer. it will idle up a tiny little bit then dead nothing. im completely out of ideas and need someones Else's opinion. please be as detailed as possible. thanks!
