Timing problem?

[marty in Ohio]

Hey, Barners,
Last week my "30 Town Sedan came home on a flatbed. It would crank, lots of gas but no start. After a trip to Snyders it now has a new coil. condenser, points, rotor, dist. body and cap. It still wouldn't run till I changed the ignition switch. Had it out today and it ran OK but a little rough. I started her to bring her home from a trip to Home Depot and she acted like it was running out of gas. She finally stalled. I got her running but she wouldn't take an advanced spark, only retarded. I got a short distance and again had to come home on the flatbed. My local Model A friend thought it was a gas issue, so I checked out the gasline, lots of flow to the carb. I took off the carb , a new Zenith a year ago, and everything there looks OK. I checked the timing and looks OK. I got her to run in the garage a little but only with the spark retarded. When I advanced the lever she died. Please help with any suggestions. I'm beginning to know the towtruck driver on a first name basis.
