Are you having running problems with the 650? Even that one is plenty big for the little 305. A 700 is too much carb.

What kind of carb do you have, and which damn pin? Are you talking about the idle screws? Missing the spring perhaps?

i have a 1992 rs with the 305/ i swapped from a tbi to carb. a 600 holley is plenty of carb for it. a 650 is going to supply too much fuel unless you jet it down and start tuning the carb.
