Hello,
I have a '69 500. It starts fairly easy, runs and idles fine. Problem is that at half throttle it seems to peak speed/power. It wont try to plane, it just goes like 5-10 mph(14' alum. boat). I cleaned the carbs, replaced fuel bulb, and rebuilt fuel pump. After all of that it seems to run smoother but no difference in speed. At WOT I can pump the bulb and it stays hard and has no effect on the motor. Brand new plugs. Seems to miss every once in a while when it is at 1/2 throttle or more. Before I cleaned up the fuel system it would try to get on plane and fall on its face and go 5mph missfiring.
What should I check first, I have a seloc manual but it doesn't seem all that helpful with my motor. The low/high speed coils in the distributor are good(400ohms) and it seems as though the rectifier is good. Things I have read about are switch box, trigger and stator but I do not know how to test them.
I need help, I have been messing with this motor for almost a year now and I have gotten nowhere. When I first got it, it would randomly work right, we would get going about 30-35mph, but it was so random/rare we couldn't pinpoint anything.
Thanks for any input.
