i have a 85 GS with a stock 12a. just got it. my first FB https://www.nopistons.com/forums/pub...IR#>/smile.gif (i now own all three gens at one time!!!)



theres a racing beat manifold on it with headers. and a holley carb.





how can i find out what size jets are in it? i think its running to rich. when i first try and step on it hard, it boggs out.



also, theres a screw keeping the two "barrels" closed at all times. why would someone do this?



i havnt checked yet, but i think its a holley 600. what size jets are recommended for my set up?





oh...and FC ignition switches swap easily into FB's???
