the big ones say 200 on the bottom.
the ones inside those say 30.
so with the 57.5 its probably setup for a 12a street port.
thats what the guy that sold it to me thought, but i wanted to make sure.
anyone have some spare jets they want to sell?

The 2 carbs I have are for a 12A and 13B SE The jet #s for both are listed 12A/13B below. The starter jet is a 760 in both of them.
The large tube you took out is the jet block. The jet in the top is the main air jet 190/240, the one at the bottom of the jet block is the main fuel jet 200/175. Pilot jet 52.5/57.5.
The pilot jets fuel the carb from idle to about 20% throttle, then the mains take over.
I've been playing with the listed jets in the bp and have had afrs as low as 10. I can't really tune the carb until I get the exhaust redone and opened up.

Okay, didn't want to start another thread, so I'll post here. I need some jetting reccomendations for the following setup:
44PHH
12a
big-*** street port, like, you can't go any bigger
RB headers
RB full exhaust
Comp 70 FP
Anybody who's run such a set-up, please tell what worked best for you
