1985 Johnson 40HP Fuel Problems

[JSmith96]

I'm new to the forum world and outboards, but I've hit a snag with my current Johnson outboard. It is currently running on one cylinder because of what I'm assuming is lack of fuel delivery to the bottom cylinder. New spark plugs, swapped coils to make sure it wasn't that, etc. Carburetors both have fuel in fuel bowls. Any and all help/advice would be greatly appreciated

Clean the bottom carburetor ------Make sure the high speed jet ( orifice plug ) in the bottom of the carburetor bowl is clean.----No money spent and easy to do.----Do you have spark on both that jumps a gap of 3/8" or more , yes or no ?
