Is there a trick/tip to tapping in the pin to lower the air plate static height to give the recommended 1 to 2 mm free play? I am still battling a warm start problem (Now only above 60degrees C after sitting a while, fires, dies, immediately restarts OK) Replacing fuel pump check valves, accumulator, fuel pump relay and injectors helped all other start conditions but this specific one. I have tried to tap the pin in with a drift and a hammer but it doesn't budge. I'm certain I have the correct one from the drawings in the manual (just to the left of the mixture adjusting cover as one stands at the driver's side fender looking down into the throat). I'm afraid to wack it too hard for fear of driving it in too far or damaging the casting of the housing.
