first runup to 4000rpm on new 912ULS

checked all pins and wires as well as coil with ohm meter

all normal

all that is left is a bad trigger coil and that means pulling the engine

Alan

engine pulled forward 8 inches

two coils had wide gaps over .25 and were regapped to .12-.14

still seeing about 250 rpm drop

going to rebalance carbs
