jack350 Posted October 5, 2009 Report Posted October 5, 2009 ok i just re-built my mates bike.. fresh crank, fresh pistons, and done by the book.. ok so i cleaned the carbs by undoing the the bowls and spraying carby cleaner... (didnt adjust floats, didnt syc carbs etc.) i was just syked to hear the bike start.. it was givin me a hard time startin so i adjusted the air/fuel mixture screw , kicked it over and it started but stoped. i then went to syncing the carbs and idle... after that it wouldnt turn on.... everytime we tryed kickin it over a little bit of fuel was pourin out of the over flow.. so i thought it was flooded so i opened the drain port at the bottom of the carbs and fuel wouldnt stop pourin out .. i knew that something was wrong.. It evently started again but reved outta control!!! my question is : if the floats are stuck open will this cause the engine NOT to start??? if yes.. wen it evently starts will it cause the engine to rev off its head without my thumb on the throttle??? PLESE REPLY !!! THESE QUESTIONS ARE IMPORTANT FOR ME TO KNOW THANKS!!! thanks guys jack Quote

Sandfrk33 Posted October 5, 2009 Report Posted October 5, 2009 Sounds like the floats are definately out of adjustment. Make sure the slides are sitting all the way down also. If they stick or are in wrong, it will rev when started. This is a carb problem. When you clean them, Use an air compressor to blow out everything. Carb cleaner doesn't get everything out of the jets and passages. Quote
