Hey I need some advice for my car. I have a 340 dart with an edelbrock 600 cfm on it. The car starts great when cold. When it heats up restarting is difficult. Any suggestions would be appreciated. Thanks
 
Basics first. Choke off when hot?
Simple test to do when hot & you need to re-start: remove air cleaner, activate throttle while looking into the primary bores. You you see a fuel stream from the pump nozzle into each bore; if you see fuel, might be lack of spark.
No fuel, could be float level, acc pump plunger worn out, low float level, fuel evaporation, etc.
 
A lot of carburetor issues are timing issues. Where is your initial timing set? Can you give us some details of the engine build please? Camshaft? Compression and so on?
