Hi,
My Force motor just doesn't seem to run very well. It doesn't have a good hole shot, and doesn't hit the WOT rpm's that it did when I first put a new power head on it. 3 years ago I replaced the power head and Checked the comp on all cyls, and it's still the same @ 150psi. I've replaced the stator, linked and synced the carbs and timing, checked timing, new plugs, rebuilt carbs, rebuilt fuel pump, and replaced fuel lines. When I first got it all back together it seemed to run fairly well, but performance has diminished over the past 3 years. Throttle and choke plates are fully open at WOT, throttle roller lines up between marks on cam, and timing set to 30 deg BTDC, but still only hit about 4200 rpms and 24 mph at WOT. Prop is 15p and boat is approx 1800 lbs. Magnet had to be re-glued in flywheel but was matched to old marks from before. Can anyone suggest what else I may have to check and/or correct? I'm running out of ideas and growing in frustration. Thanks!
