    I personally would start with a replacement carb. Im sure someone near you can lend you one. If you get stuck, I have about 1000 OMC carbs here, im sure I have one I could mail you!

    Are you certain there is not a water intrusion into the cylinder via exhaust gasket washing plug and causing your issue? It would appear to be lean (not enough fuel to properly burn). Any water droplets on clean plug? Have you tried replacing the plugs?

    Have you inspected the crank seals? If mag plate is off, just pull the top off and replace.

    Hopefully you don’t have to reseal the block.
