I’m using a gauge with a short hose and threaded plug hole end.The numbers I get are consistently 80 lbs by hand and barely 70 with drill.I can use the drill,lay it down,rope it over 5 times and get it up to 80.For comparison I have a good runner of the same model that is steady at 85lbs spinning it with drill or pulling it over by hand.This motor absolutely will not Idle or start without a shot of gas into intake.I have taken carb and mag plate off the runner and put them on it with no change.It has to be an issue with the power head.The higher number says it should idle but the lower would explain why it doesn’t.I’m stumped.
