Carburetor FAQ’s

Q. What is the difference between an automotive and marine carburetor?

A. Although physically similar both carburetors are designed specifically for their environment. In the case of the marine carburetor, special care is taken to make sure no fuel leaks into the bilge. Special overflow channels on the vent tube, channeling on the throttle shafts, and a fuel pump overflow are all important in the marinization of the marine carburetor.

Q. What information do I need to find the proper carburetor rebuild kit for my application?
A. Most carburetors have either a metal tag on the front of the carburetor or a manufacturer’s production stamp on the body of the carburetor. Either of these locations should provide the numbers needed to procure the correct rebuild kit. If these numbers cannot be located or the tag is missing, the Sierra catalog can cross most make and model information to the correct kit.

Q. How can I prolong the usable life of my current or recently purchased remanufactured carburetor?
A. Proper fuel maintenance is the key to a long carburetor service life. Make sure all filters are changed at recommend service intervals, quality fuel is utilized and if the boat is to be stored for extended periods of time use a quality fuel stabilizer.

Q. How can I tell if I need to purchase a remanufactured carburetor vs. installing a rebuild kit?
A. Generally speaking, a rebuild kit is only good on a unit with minimal wear (low hours of operation) and no obvious sign of corrosion. If your unit exhibits either of these conditions, your better off purchasing or installing a quality remanufactured unit.
