Cleaning Mercury Marine Carburetor, Part I

Mercury manufactures a number of outboard motors with carburetor intakes. Learning to clean these carburetors is a moderately difficult endeavor. You will need: various screwdrivers, shop rags, jet pick, safety goggles, compressed air and air nozzle, and a carburetor cleaner. It doesn’t hurt to pick up some Mercury 2 cycle oil while out getting supplies.

Begin by removing the brass screws on the side of the fuel bowl with a flat screwdriver. Drain the fuel from the carburetor and use a shop rag to absorb the excess. Using a number two Phillips screwdriver, remove the four fuel bowl screws and lift the bowl up and off the carburetor body. Take your jet driver and remove the main jet and pilot jet, taking care not to damage the brass jets.
