Went to a great car show this past weekend but have run into an issue since.
The car ran great at highway speeds and at idle to and from the show, until I pulled into the street I live on when the engine stumbled and died as if it was out of gas.
I cranked the engine and stabbed the gas a couple of times and it started right back up, but was/is running ragged at low rpm/idle. If you slowly depress the gas pedal, it will stumble and try to stall unless you feather the pedal to get through that point and up into the higher rpm range, and it will then take off just fine and run at speed with no issues. Once it gets cold, and you tap the pedal to set the automatic choke, it fires right up and runs fine on the fast idle cam of the carb, but then as it warms up and the choke is wide open, I can't get a good low speed idle and it wants to stall under load until I get past about the 1500 rpm mark, then all seems to be well. Did I suck some crap from my 54 year old gas tank into the idle or low speed circuits of the carb? Did something change inside the distributor? Is the fuel pump only doing its job at higher rpm? I'd prefer a more logical approach to troubleshooting as opposed to shotgunning and throwing parts at the problem (fuel pump, carb rebuild, points, condenser, vacuum advance, etc.)
Any suggestions appreciated.
