Default Holly 4150 Idle Adjustment?
Hello all,
I bypassed my TCS valve and went strait to the vacume advance on the distributor with my vacume line, set the timing to 34deg, all in at 2700RPM. After the adjustments my idle jumped up to about 1000RPM with the vacume connected.
My question is, is the idle agj on the dirvers side of the carb, inside of the throtle assembly? I will eventually get a Holley book but I need to get the idle back to about 700 for now.

Thanks in advance

There will be a screw on the driver side of the base plate that you will see touching the throttle arm. Just back it off.
