1989 Quantum bass boat with a 85HP Force motor..originally it was only firing on 2 cylinders and I traced the problem to a bad CDI....replaced that and all 3 fire now. The problem now is we went out to test it today and it was running great for the first 10-15 minutes at WOT. Then when throttled down to turn around we tried WOT again and it just kept bogging down....could barely keep the engine running in gear with very little throttle....any more it would die. Then it died off and wouldnt start. I went back to the engine and adjusted the fuel/air screws and we got it to start and idle.....it would run in gear at very low throttle again. The bottom carb when I was adjusting it made no difference...the top 2 we could hear the engine rev up or down depending on the screw adjustment. So Im fairly certain this is a carb issue but I dont know how to properly adjust the air/fuel mix or if theres another issue I should be looking at. Please help....had plans to go on a striper trip tomorrow.
