i got a carb that was fine half a year ago now it pours from drain even after clean.  it passes a blow in the gas line test when i flip carb upside down.  i think the spring in the needle is shot.  does anyone use another style needle like a rubber tip one or one that has no spring?  i order a new needle so hopefully thats it.  the guy had sold 126 of them so far.  
i saw on ebay one guy selling a bowl and floats used.  it seemed like he had replaced the original floats with later style brass ones.  has anyone done this?  he was calling it a hop up bowl.  or anyone know where to get brand new floats?  my floats seem to float but geez think they are old. 
recently i put a rear tire on and man it was a lot more complex than imagined.  there was like 2 nuts and the spacers had flat spots and would only go in with redpect to the flat part.  i got wheel off ebay in parts so a little more than just repeat in reverse to get it going.
whats funny is i went to put on muffler and couldnt because the head was on backwards even though it ran fine with it backwards with no exhaust.  i was shitting for a min until realized hey its backwards.
thanks
