How many of us are there? Owners of Dodge based RV's?

Sorry if this is too basic, but the choke plate is closing when cooled down? With a bit of spring tension holding it closed? The bowl going dry was from a syndrome called percolation, where it was so hot it boiled dry out the main nozzles in a hot soak situation(shut down, air flow stops). But the thermoquad has a phenolic bowl section to reduce/eliminate this.
A cold engine requires a richer mixture to start, whether its the fuel pump squirts or the choke plate cutting off the air.
