We start by investing in an inline spark tester .
This way you will have cut down the things to check by 50%.
While you are waiting for the tester to arrive remove the float bowl.
Put a catch pan under it so you can see what comes out when you try to remove.
Better than average chance there will be water in there.
Some idle circuits draw fuel from the top of the float bowl.
Water is heavier than fuel so it sinks to the bottom.
For the first seconds the engine sucks fuel from the top of the float bowl , then as the throttle opens up it sucks water from the bottom and stops.
