An EAA member called his brother-in-law to ask if he knew of a way to hold the spring and plastic cup while changing the jet needle clip setting on a Rotax engine. Finding no solution, he decided to invent one; the handy Kwik Tune, a timesaving tool he launched at Sun ‘n Fun. Kwik Tune helps remove and reinstall the aircraft throttle cable, cover, spring, and slide in a Bing carburetor.
