The Ford Barn

I've done some research on this topic but want a little more feedback or reassurance I'm heading the correct direction.

1950 Merc fires up cold like its fuel injected, half a crank and its running.
Electric fuel pump, regulated to 3-4 psi with a kill switch. My battery is 2 years old, load tested good a couple months ago - still 6 volt. I've replaced everything relevant to spark except the distributor itself. New battery ground wire to motor size 00. New factory starter wire and relay from shoebox central. I've pulled the starter, cleaned the brushes and grounds from the pan to the starter. All wiring from the firewall forward is new. I added a 1/4'' spacer made out of garloc gasket material to act as a phenolic spacer.

The only things that I have not done is install a phenolic spacer or move my coil from the motor and away from the heat. These are 2 things I plan to do next.

All of the things I have done were not for this problem specifically, most was done preventively since she lived in a barn for years before I got my hands on it. I do have a 12-volt conversion and a full wiring harness waiting to go on whenever I get time. Id like to solve this while it's still 6 volt as everything is highlighted and I won't be covering up my issue with 12 volt.

Now that you know where I'm at and where I'm heading none of the above has helped with my hot restart issue. I even go as far as to shut the fuel pump off before I park and allow the motor to run out of gas. Before I restart it, I let the fuel pump run for 5-8 seconds to refill the bowl with cool fuel - this has proven to help but only the slightest bit and still requires multiple attempts at starting. I do not touch the gas pedal while trying to restart, I have found not messing with the pedal allows it to restart sooner. It also cranks slower while trying to hot start vs being cold. Any other suggestions?
