Abstract
A carburetor fuel valve adjustment and limiter assembly for a combustion engine limits the maximum and minimum fuel amounts delivered through the valve of the carburetor. A needle valve of the adjustment and limiter assembly cooperates with a collar and pin generally located axially inward of an enlarged valve head. The collar of the limiter assembly is arranged telescopically with a valve shaft and yieldably biased to lock to the head when moved in an axially outward direction. When locked, and upon rotation of the valve, first and second stops carried by the collar are arranged to bear on a stationary pin carried by a carburetor body. During manufacture, the collar can be pushed axially inward against the bias of a spring to disengage the collar from the head to permit rotation of the needle valve while the collar remains stationary for unlimited adjustment of the needle valve.
