51 Fleetleader flathead 6 - stalling when hot and under load


When the engine is hot and under load, it stalls out and won't start until it cools down.  Will start good when it's cool but then stalls out again after running and under load.  Any suggestions what could be causing this situation.  I have checked the fuel filter, fuel pump and has spark.  The engine runs with heat guage at normal.

Have you checked your coil? They can be ornery when hot.

The heat riser valve is maybe stuck in closed position, it's a must to have this thing work properly (heatriser valve).

When the engine stall check if the acc. pump in the carb inject gas into the intake when you depress the acc. linkage, if not your engine maybe lack of fuel.
