A throttle lever 793 to suit the UMS 5-100cc — the five-cylinder 100cc four-stroke radial from UMS.
On this engine the component is the throttle lever (621 type) linking the throttle servo to the carburettor.
Why this part matters: replaced when the lever or its pivot wears, which shows as an inconsistent idle. Supplied as a pack of 5, which is how these small parts are normally bought — you rarely need just one.
Fitting note: Set the linkage so the carburettor reaches both stops without binding.
