About 3 weeks ago, I drove my '73 duster with no issues. The following weekend I got a few blocks and the car cut out. I had to pump the gas many times before attempting to start to get it running but it would cut out almost immediately once in gear. I can idle fine and it revs up smoothly if in park/neutral. But once in gear I only move half a block at best before it stalls.
The carb is a quickfuel and practically brand new, maybe a few thousand miles on it. Ignition system was redone this past fall, ditching the old ballast for an msd 6AL and new coil, plugs, and wires. The fuel filter itself isn't that old either. I'm thinking the fuel pump might be the culprit because I'm not really seeing any fuel from the carb's sight glass. I don't have a gauge on hand to check fuel pressure, but what should the psi be?
Simply put, engine seems fine at idle but stalls when in gear.
