ok, all fuel filters changed (1). no kinks in lines, clear pick up tube. still only getting 2200 WOT RPM with 17 Pitch, sure a little small for my 1984 mercruiser 140, 19 pitch on the way. looking at compression test numbers this week, i notice some blow by, but it ran at 4500 WOT RPM 3 times, also hit 32-35 MPH 3 different times. could all this be just weak spart? distributor counter weights not advancing the spark as they should.
