HOLLEY CARB
Holley street avenger 770 vacuum secondaries. Have two power valves and assortment of secondary springs. Too large for my car. Does need rebuild. Have kit but used bowl and plate gaskets to change power valve. I thing some passages on metering plate may need hot tanked. Ran rough at steady speeds as well as stumble on accel.$150.00 plus ride.
