Things to check, CO when hot. Also check the height of the fuel plate. If the adjustment is off then the plate maybe be to high and not allowing enough movement.

Why will it start cold, well the CSI is doing its job. When hot it shuts down and lets the plate inject as it sees demand form the motor darning cranking.
If I feed it a little throttle, it will start - but, if it does not start on the first crank, forget starting it within the next 15-minutes. No throttle, half throttle, full throttle does nothing - it's as though no fuel, period. I also sense on start the engine is lean for it does not come alive the same as when it's cold. Kinda get the feeling it's not going to keep running, then it does.
I believe you may have put your finger on the problem. I disassembled the air box to polish it, re-assembled as I believed it was. Did not know fuel plate was sensitive to height or for that matter adjustable. It does seem to sit slightly above level in its cavity. The cavity is closed but more than 1/2 the thickness of the plate is above what I perceive as 'neutral.' Is the adjustment straight forward? Easily accessible in an engine compartment without room to work in?
Many thanks for your help.
