On c-206 with conty-520, I usually open the hatch on the top of the cowling after the flight, so the hot air doesnt collect inside the cowl.
My procedure for hot start is: master-on, mix-out, throttle-open. I then push fuel pump on for about 10sec. After that, I prime the engine for about a second or two (mix-in, throttle in, fuel pump-on-off). Then throttle 1/2inch-in, mix-out. Then I start to crank and slowly advance the mixture in. At about 2/3 mix-in the engine usually starts.
Good luck :-)
