    FYI, those are gaskets for the side plates on the intake manifold and the carb bodies, not diaphragms.

    Finally had to take it in to a mechanic. Frustrated with issue. It was a plug wire.... it would start arcing when under load evidently. I had initially noticed that cylinder had no spark, pulled wire to check resistance and it must have completed the circuit:"good enough " again to not misfire not loaded down. In fact, the mechanic put spark checker on it and everything looked great until he did a balanced cylinder test which I did too but while the boat was in the water so I couldn't see it arcing when the wire was disconnected. $100 diag fee + $50 tip for squeezing me in and we're on the water like normal. Hope it helps you. My stator still reads low but it's charging and running fine. My sneeze is still there.

    First think i check when the engine is sneezing it make sure its reaching operating temp. If you have an overcooling problem it can cause that, along with a lot of other things but thats were i start.

    What did you do with the timer base and stator you had on order?

    Still have it. I may go ahead and throw them on. Then again, they are still sealed in boxes so I may return.

    Update
    I swapped out the timer base today and when I had the flywheel off and inspecting everything I noticed a couple of the windings on the stator were blackened and not shiny copper like they should be.
    Plus they werent connected solidly to the stator frame like the others. That sounds bad to me.
    I did get it started after putting everything back together but did not run it long enough to blacken the spark plug on the cylinder that I was having problems on.
    What kind of problem would the bad coil blocks on the stator cause?
