Also I know that there is a drain line from the silencer to the powerhead, If I have no silencer should...

    power surge... wants to really go

    Well I feel like I am almost there with my 1972 65 hp Johnson. At first it had slow speed problems but would really run on the top end, then I adjusted the carbs for great low and mid range put it never turned the rpms it did before on the top end. I rebuilt my carbs a few days ago and yesterday...

The rod turns 90 degrees and goes into the timing...

    reading plugs for mixture

    I've taken my boat out a few times now and am trying to get it dialed in. It has a 1972 65 HP 3 cyl johnson on it. My manual says to adjust the lower 2 carbs at 650 rpm and then do the upper at 1100 rpm. Since I have no tach yet I am doing it by ear and have all 3 low speed needles (high speed...

    difference in loopers and other

    I am curious as to what it means for a 2 stroke to be loop charged. What other types of 2 strokes are there? I know my inline 3 johnson is loop charged. Is a crossflow different from a looper? Thanks for sharing the knowledge.

What does it send a signal to? There is...

    all 3 lost fire

    Just before determining that my head gasket was blown, my 71 3 cyl. johnson 60 died. I checked the spark and there was none on any cylinder. I have a manual on the way but what can I check in the meantime? Are there points on this motor under the flywheel I can check? I would guess it would have...
