About this part
The carburetor on your B31 blends air and fuel before the mixture reaches the combustion chamber. Poor cold starting, a lumpy idle or a smell of petrol around the intake point to gummed-up jets or a leaking float chamber.
Frequently asked questions
What should I check when buying a carburetor for the BSA B31?
Compare the type designation and bore stamped on the body of your B31: one series often ran several carburetors depending on engine and market. Ask whether jets, float and throttle spindle are still original and free of play.
Used carburetor or a rebuild kit?
As long as the body and spindle bushes have no play, a gasket set with fresh jets usually brings a carburetor back. Once the throttle spindle is worn the engine draws false air, and a good used carburetor is the cheaper answer.
