    1990 Johnson 90HP 2 Stroke Bogging - Help!

    No, the primer doesn't really get firm which is why I think there was a leak. The dark plugs are on the side away from the fuel pump. Will check the gap. I am comforted by the fact the compression is pretty even but unsure if is above 90 at all. Will check a third time but with a different...

    1990 Johnson 90HP 2 Stroke Bogging - Help!

    Yes, the two starboard cylinders. I will redo the compression test. I cleaned them with carb clean (non-rubber parts).

    Thanks! I guess I will re-test the same way with a new gauge. How would I remove the 4 bypass covers to look at pistons and rings. I have heard older 2-stroke motors can run just fine on 90psi. Is that true. Again, thanks so much!

    Hi all, I recently purchased a 17ft 1990 Proline center console with a 1990 Johnson 90HP 2-Stroke motor. The motor came with the VRO pump removed and a fuel pump installed. The motor had no spark out of two of the four plugs but I quickly noticed it was missing one of the two CDL powerpacks...
