Reply To: Briggs & Stratton / outboard carburetor

[Mumbles]

You don’t mention what model number the motor is but I’m thinking it’s the one with the square gas tank above the starter and the up draft carb with a brass float? It has a module so it can’t be the points or condenser. What about the spark plug? Small engine plugs tend to go bad so it wouldn’t hurt to put a new NGK in it. Fuel flow? Is the gas fresh and does the gas flow freely out the hose at the carburetor end when the shutoff tap is turned on? The brass float can develop a leak to and get heavy which causes flooding. Carbon buildup on the valves face or seat would increase the clearances but without knowing the model number, I don’t know what your clearances should be. Here’s some specs:
