Ok, I am getting closer on this old 1963 75HP Johnson.
It was not running a month ago. I have replaced the plugs, plug wires, bad cam on the magneto fly wheel, and I bought a carb kit and cleaned the carb.
The boat will idle nicely here at my home finally in a barrel, but I finally took the boat out on the lake today and it seems to have a fuel issue. I can still get it to idle nicely on the lake, but It is somewhat "sputtery" on acceleration and is very inconstant. If I set in the low speed carb adjustments then it won't start, If I open then too much it obviously floods. I can get it set so it will idle nicely but when I try to accelerate it does not have a nice smooth takeoff, It has a grumble sound and then while not even touching the throttle there is a sudden burst of speed. I have to knida ease it up in steps and , I push the throttle forward and there is a delay in acceleration, then I throttle a bit more and there is a delay again and then is speeds up after a delay again.
It finally hits top speed but after a while it starts to hiccup a bit and it really bogs down in turns.
One other thing, I am noticing small drops of fuel in the water behind the motor...what would be causing this...I guess it might be coming from the exhaust?
Any help on this would be appreciated.
Thanks
