However, I have one issue with hot starts that I didn’t have with the dualplane and the 770 avenger. When the motor is warm it needs maybe 3-5 seconds on the starter and half throttle before it starts. Starter turns fine. I’ve leaned it out as much as possible, played around with secondary idle throttleblade opening to prevent too much exposure of transfer slots and even put in a phenolic spacer for heat insulation but I still can’t seem to solve the problem. Looking down the carb after I have shut it down the throttle blades are slightly wet of fuel and it smells a little from fumes standing next to the car.
Any suggestions to what the "problem" could be?

Have a look at your accelerator pump check valves. Sometimes during a hot soak fuel can drip out of the accelerator pump discharge nozzles, wetting the throttle blades and dumping a load of gasoline into the manifold making it flooded on a hot start up.
Check the float level also.
How many turns out are the idle screws ?
What size are the idle jets and idle air bleeds ?
