    Re: Johnson 9.9 Timing / Sync hash mark way off. Ok..progress! I now have the throttle sync'd but I have not had an opportunity to test the motor yet as I spent all night getting it right and it was too late to fill the barrel and wake the neighborhood with full throttle testing. Basicly I...

    Johnson 9.9 Timing / Sync hash mark way off.

    Re: Johnson 9.9 Timing / Sync hash mark way off. Joe, I'll clarify a few of your questions: "What does this mean (fatter)?" - The cam itself (the black adjustable plastic wedge on the timing plate) has a screw. I am attaching a picture that I took from Leroy (thanks the machinist). The...

    1955 Johnson CD-12 Engine Knock

    I have been using a 1955 Johnson CD-12 all summer with no issues. Had it out the other day and after about 5 minutes it started bogging down, and before losing all power, it developed a nasty knock. I brought it home, and re-started the motor in a barrel of water. It started on the first pull...
