|Rebuilding your Stromberg EX Carburetor|
The most important thing is to take pictures as you take it apart in case you have questions later.
Soak the carburetor in carburetor clean from your local parts store (not the spray).
Follow the directions on the can. You can discolor your carburetor if you leave it in too long. Don't put any rubber parts in the solution.
Wash all chemical off in hot water.
Blow out all passages.
Polish the pump well (in the carb, not the pump itself) with crocus cloth.
Ethanol gas has little lubrication so the pump will need a smooth surface.
Do not put any pressure on the needle & seat. The viton tip can be easily damaged.
