1987 Force 125 (uhh)

Ok here is the problem. I go out and run I can run full throttle but as soon as I get it down to idle or wakeless speed im screwed. I can not sustain full throttle any more. I rebuilt the fuel pump. I did that becuase it would get up on plane and die. Now it drops 1000 rpm and then drags back up. I will be running at 4k and it will drop to about 2700, feels like Ive hit something and then it speeds back up. Help. I pulled the fuel line off the outgoing side of the pump it was flushing lots of gas. Any ideas would be greatly appriciated.ThanksZach

Sounds like the engine loses a cylinder. Change of plugs to start with. Do a spark check when it acts up. Compression check would also be in order.

Check all your electrical connections, esp all the wires that tie into the panel. We had a similar problem, ended up being a lose connection.

comp fine, electrical fine(choke works better now)but still have the same problem.I really think that it is the fuel delivery, I had the fuel pump rebilt but to no avail.when it starts to act up I can squeez the ball pump and it will go away.Anymore ideas??? thanks

is the tank vent working

[roscoe]

Is the ball pump being sucked flat?Make sure tank vent is open.Replace the entire fuel line, from the fuel pump to the tank.Verify the fuel pump is working, be careful.Check the float bowl in the carbs, clean it out, check/set the float position.

Check for krud in the vent hose. Plugged hose and it will starve the carb for fuel. I had a spider nest (small) in mine.
