Joe, the choke heat pipe connection looks suspicious. It appears as if a rubber hose connects the choke housing with the pipe. There should be a direct connection of the pipe to the housing.

I had good results adding diesel fuel to the gasoline when I refueled. A gallon with a full tank worked wonders. This was when I had the 47 Custom Clipper with the same engine as your 40.

The Hot Rod magazine article offers good advice about insulating the carb. Also, insulating the fuel pump is a good thing to do too. Vapor locking primarily takes place in the non-pressurized part of the fuel system.

How did adjusting the idle mixture go? Good advice has been offered on this by others. If you can screw the jet screws in all the way and the engine continues to idle, then you have a flooding carb issue.

I still have the BMW.

Happy New Year.
