    Surging Johnson 6 hp.

    I haven’t done a spark gap test in a while but I’m thinking it jumped a 1/4” gap no problem. Will check and try again.

    Surging Johnson 6 hp.

    Compression check was 90/90 so it’s good. I’ve not checked the temperatures, but I’ve got a thermometer I think would work. I will swap the magneto components to give them a try. Both these motors are 1976 so I think should line up well. This 6 hp is a gorgeous Johnson motor so I’m pretty...

    Surging Johnson 6 hp.

    I rebuilt magneto for 2 reasons. 1. Id never rebuilt a complete magneto and this motor is in really great shape so I wanted to try it. 2. It was surging and it thought it the surging might be motor running on one cylinder when it would just get intermittently weak.

    Surging Johnson 6 hp.

    I put in all new Sierra points, coils and condensers, a few months ago suspecting the same thing. I still have the same symptoms even after rebuilding the entire magneto. I also put new coil wires and spark plugs.

    Surging Johnson 6 hp.

    I checked the bottom jet and it looked pretty good. I soaked the while carb in Berryman for a couple hours last night and just to be sure. My fuel is probably 2 or 3 months old. I have a 4 HP motor that I am working on now at the same time that has no surging, so I think the fuel is ok. This 6...

    Surging Johnson 6 hp.

    It has a brand new water pump that pumps incredibly well. It had a clog in it that I had to resolve last fall, but that’s working great. I’ve also replaced the thermostat.

    Surging Johnson 6 hp.

    I rebuilt the carb. I don’t have a book: just replace all the parts in the Crowley marine kit and turn the low speed know out 1 and 1/2 turns and fine tune from there. If there is more I’m missing that’s news to me. I probably need to download the red book from the aomci sites I’ve got a service...

    Surging Johnson 6 hp.

    I have a 1976 Johnson 6 hp motor. I am having trouble with intermittent surfing at wide open throttle. It will run strong wide open then get weak. I’ll throttle down and I can throttle back up to wide open throttle strong only for it to surge again. This happens under load and running in a...
