bought a basic rebuild kit from a local supply house and was very surprised to find it came with two sets of jets. one marked as **J1 and the other as **J2. i ended up ruining a pair of each just trying to get the old jets out and the new ones in. good news is i'm rebuilding two cars at the same time. so one car is going to be pretty much just a stock 2.4 while the other will be slightly modified (ignition, shaved head and header). which jet size is which? and which jet should i put in the modified car?

while we're on the subject, maybe someone can explain what the deal is with the two different needles in the float bowls? the ones in my kit are both the same but the ones that came out of the cars are different. the needle for the rear bowl appears to be some two piece design. any ideas?

Have you tried contacting "ZTherapy" ...the SU experts?

not yet, i will though. during disassembly, one of the jet assemblies disassembled alot more than it should have. (woops!)

as funky as this particular carb was, i can only imagine how bad this car ran before it was shut down.
