    How do you set the points on 1967 20hp Johnson?

    There is no port on the flywheel to set the points, so i am guessing i have to do it with the flywheel off. How do i set them? i can only think of using an older flywheel from a 1958 johnson with the port. Then replacing the original flywheel. Will this work?

    Classic case on a 1967 Johnson 20hp

    This problem is a classic on here but i never really paid attention to them. motor runs sluggish at the highest idle. When i pull the choke halfway out, it revs up, and i can decrease the throttle as long as i am holding the choke. Basically it runs like it is supposed to with half choke...

    12hp Gale Buccaneer update

    12s12 or 12s13.. I finally got back to tinkering with it. I checked for spark on both cylinders, top was strong, bottom was very weak although it popped me pretty good holding the spark plug boot. I figured the connection in the boot was bad, so i replaced it. Spark was good after that. I...

    What's the difference b/w 1988 30/35 hp?

    I know in 85? the hp rating was measured from the prop, so the '84 35 was the same motor as the '85 30... in '86 the 35 was a detuned 40, but in '88 the 35 returned to the 20/30 family. What exactly happened in 1985-87? and how did the OMC engineers pick up another 5hp? was it just a mistake...

    12hp Buccaneer runs like crap after rebuild

    http://www.youtube.com/watch?v=62W8SXnJyj4 it ran before it had a knocking problem, which was apparently caused by the exhaust ports being plugged with carbon. all the ignition components are new, set, and produce a strong spark. The carburetor is from an 18hp and was rebuilt last Fall. Had...

    got used coils today bought on ebay, they were said to have come off a perfectly running 15hp. I test the spark, 1st cylinder, no spark, 2nd cylinder, excellent spark. Interestingly on the second cylinder, with no spark plug, a spark jumped a 3 inch gap to the rewind starter. Now before i...
