Do you have a fuel pressure gauge on it?

Doing better! 67mph with the 4 blade. Changed jetting, 78/94 at 4900/5000. 3 blade should get 400 more rpm and a bit more mph. Oil temp is 170. Used a thermal gun on various spots. 170 is at the filter and fittings.

Fuel pressure is 7lbs at idle and 4/5 at wot

Fuel pressure at wot is on the low side.
