|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.|
I used it on the 503 Rotax DCDI Engine. I quite swearing as soon as I received this in the mail. A Cool Tool for sure.
This is designed to tune 2 stroke carbs. Does not work on the 9 series.
