Has anyone had this Rochester 2 barrel 2G issue, have searched and not found anything. After replacing my 2 barrel cast intake manifold with an aluminum edelbrock (225 v6) my carb started sticking above idle (sticks at 1100 RPM) when I take my foot of the gas. If I blip the throttle I can usually get the engine to drop down to idle, 6-700 RPM but that’s annoying to have to do at every stop. I can open the hood, rev it up by hand a little and see that the idle stop screw doesn’t quite come back to the stop (the cam) when I let it go. If I give the linkage a little push it does return to the stop. If I turn the motor off and try the same thing the carb returns, to what would be idle (with the idle stop hitting what it should for proper idle) without needing the little push. The only redeeming thing about this is that post manifold swap its pretty hard to get the motor to come off idle with the gas pedal. Hard enough that’s it tricky to get the jeep moving smoothly. I have pulled apart the carb and the throttle plate and shaft move freely and I don’t feel any obvious binding. Its almost like engine vacuum is trying to hold the throttle plates in closed position when coming off idle but I don’t know why that would affect the return action. I don’t want to add another return spring since that would make it harder to get off idle and it returns to idle position with the motor not running as is.
