Demon Sizzler still rebuilding carbs?
Try this guy:
http://www.deanoscarbs.com/
He's got a *very* good rep with a lot of "stock carb" class racers. I haven't bought a carb from him, but have talked to him on the phone a couple times. Seems very down to earth and knowledgeable.
Demon Sizzler will be missed for sure.
