any chance youleft some gas with oil sit in the bowls. might have pluggedup the pilot,

 

i would pull carbs off clean them very well, check your reeds make sure you dont see any light thru them. and go from there.

well it should start with either 48 or 50 pilot, unless that circuit is plugged. but if the carbs are good and clean you better start checking spark. you might be getting intermittent spark and sometimes itll start and run fine and other times it wont. ive had that happen to me before..are your plugs fouled by chance?
