    1995 Mercury Sportjet 120hp bottom carb problem

    I have been working on a 1995 mercury sportjet 120hp and have good spark and compression on all cylinders. The engine hasn't been running very good and after doing tests I found out that the bottom 2 cylinders are not getting fuel, since the spark plugs are dry. This leads me to believe...

    Evinrude Fleetwin High Speed Needle Problem

    1957 Evinrude Fleetwin Carb Problem

    My evinrude will not run very good at all. If I do get it to start (take around 5-10 pulls) it will only stay running for around 10-15 seconds, and can not idle low, or be put into gear without it dying. I have replaced coils, points, and spark plugs so those are not the problem, but I believe...

    Why do Points Need to be Spotless?

    From what I have read the points in a flywheel need to be spotless, and cant even have a fingerprint on them. I am just curious why since to my understanding electricity just goes through them. If anyone can explain this to me it would be greatly appreciated.

    I have been having trouble getting my evinrude fleetwin running for a good amount of time now.

    1957 7.5hp Evinrude Fleetwin Fuel Tank Problem

    I have a 1957 7.5hp Evinrude Fleetwin with the old style fuel line that has a gas and air line. I have noticed that when the gas tank is higher in the boat, the motor is more responsive and much faster. Any reason why this happens and is there something wrong?
