    20 hp Mariner No spark

    This is what it sounds like after all the timing adjustments and other adjustments in the post above with the timing procedure. Very simple. Going to take it to the lake tomorrow and do the full throttle timing. Does this thing just run rough like this? Should it be smoother? Timing is on spot...

    20 hp Mariner No spark

    Ok that works, another question I have, the spark plug wires on the motor currently are a 7 inch and a 9 inch wires, I ordered a new 7 inch one as that one was shocking me and needed replacement, on marineengine.com they have only the 9 inch listed, should I do 2 9 inch plug wires or just go...

    So I put the new coils in and tested it out, I touched the boot on top spark wire and I got shocked again, shut it down and inspected the boot noticed a small cut in the boot, put some electrical tape on it and no more shock, but it still seemed like it was missing or something... I hooked up...

    Yeah I was thinking about the rebuild kit over the new one, I took this one apart once already and inspected the Diaphram and check valves and they looked like they were in good shape, buy never hurts to throw a 6 dollar Diaphram in just to be sure. I love the advice!!

    Like one of these, if its clearance issue, I can just swap the base of the current one of the engine.

    Would this fix a qeak pump? Or would I need to get a new pump?

    And I'm sure rebuild kit is cheaper then new pump, do you think rebuild would be sufficient?

    @racerone , with cowling off it was similar, here is a video where I take it off, you can see the exhaust here as well, it was blowing away towards the garage.

    20 hp Mariner No spark

    So I tested and it was missing, inspected the coils and when running the top spark plug wire was shocking me but not the bottom. I ordered new coils. They will be here Monday. I took the boot off the back of the coil and this is what I found. Broken pieces, would this cause a miss?

    I did have 2 x 4s under the tote...lol that's what broke it. Well I swapped to the old condensers and that miss is not there. I got champion J4C in. Not sure why the condenser did that either, I know when I test it, the readings go up faster then the others, and to be clear it was only the one...
