welli took it apart again for the umteenth time and still remained baffled,ive never been baffled like this before,this has got to be one of the most baffling things ive ever seen.then finally some one mentioned baffle and thats the only thing on this carb that i didnt look, at or replace and sure enough it was pointing down just enough so that after everything got good and hot it would hold the float open.i turned it upside down and put every thing backi together and i am no longer baffled.thanks all for your help it could of been any or all that was sugested.But Dwayne gets the cigar.
