I cannot get my 1725cc engine to idle properly. I recently installed an Alpine Innovations carb/manifold setup. The car ran great after the installation, but I subsequently ran into a problem getting the engine to run. (I don’t believe my current issue has anything to do with the AI equipment.) I’ve replaced the spark plugs, plug wires, coil, distributor, and ground strap – all to no avail. The only way I can get the car to idle (and even then it idles rough) is to have the idle mixture screw 4.5. The timing is slightly advanced but only because the vernier adjustment on the distributor is already up against the block. My distributor replacement involved replacing a Pertronix unit with a points-style distributor recently rebuilt by Advanced Distributor. Any suggestions would be greatly appreciated.
