Best method is to Vent run the engine (Dry motor) it to 15% N1. Wait for the N1 to drop back to 0% N1 then start it.. In my experience, if the Temp is below 200 deg on fuel input, she will not hot start..
However, do NOT attempt to modulate the start (using fuel flow lever) at all. This messes with the fuel bellows and will constantly give you hot starts. The fuel flow must be moved into the idle gate for start.
PM me if more info is needed.
