Rochester 2G
« on: September 08, 2013, 03:19:52 PM »
 Cliff or anyone,
 I have a '73 C50 Rochester 2G 2-BBL carb. What size bolts do I need for the carb flange (throttle body) to intake? I lost the original bolts. :( I assume the bolts would be 5/16 fine thread (not a 100% sure) and what length? What should I set the idle mixture screws to? 2 turns out? Thanks! :)

If I remember right, weren't the idle screws set out about twice as much as the QJ? Had trips on a 65 Goat many yrs ago, and think I remember them being about 4-5 turns out.
