I have a stock 350 in truck and has developed an irratic idle after driving for a few minutes, particularly noticable when running air conditioner. Gave truck a tune up(cap, rotor--hei, plugs, wires, fuel filter) wonder if carb is problem. I'm running 8btdc on timing with an idle in gear of 700 but even with the strain the ac puts on the motor I would'nt think I should have to re-tune the engine for air use. Carb is edelbrock 1406/elec choke. Basically feels like the truck is flooding when using the air. Help??
