Hard Starting when warm on a 1940 120 Convertable

Posted by robtroxel On 2012/5/17 11:30:31

This car starts great when cold. So far the carburator has been rebuilt, an Auxillary electric fuel pump was added to the fuel system. Added two 6 volt Optima batteries in parallel and replaced all the battery cables.

Car reluctantly starts when warm (within 5 minutes of shutdown) about 50% of the time and requires at least one pump of the gas pedal when it does start. If the car sets 20 minutes, no problem.

Could this be a timing issue? Too much advance? Choke is working as intended and is in the open position when warm.
Should we replace the coil snd condensor?

Any advice is appreciated.

Thanks
