Not mine. It’s my neighbors. Runs solex 30 pict 2 with a Pertronix module. Car runs fine. Hard to start sometimes unless he pours gas down the carb throat. Runs great once it’s going. When it warms up and you come to a stop, it will stall out.

Rebuild the carb.
Look for intake leaks when hot.
While you’re at it, do a compression and leak down test, check torque on the heads and adjust the valves.

For the starting issue, check the operation of the accelerator pump output, and check to make sure the choke is working properly.

For the stalling when coming to a stop, as suggested, check for vacuum leaks.

The engine only has 2000 miles on it. Valves are adjusted. Where would you check for vacuum leaks on the car? I’m going to see him tomorrow.

Check the entire intake tract for leaks; manifolds to heads, manifolds to intake pipe, intake to carburetor base, throttle shaft bushings, and any vacuum lines that are fed by the intake BELOW the throttle blade.

Stalling is probably improper intake heat, Starting issue improper choke setting. Could be alot of other things, but these are common issues
