Send the carburetors to SISF
Straight up on this. I live in not so sunny Wisconsin, but we do have the Packers!
I send my float bowls to Steve USPS priority mail on a Monday and had them back either that same Thursday or Friday. I don't recall which day exactly, it was posted pre-crash on the old forum, but in any event, I dare anyone to beat that as far as service! Quality of workmanship is also second to none. If you have to save up for the mod, do it. $80 for this beats untold numbers for a rebuild or replacement.
