Hello all, we recently acquired a beautiful 1939 Piper J-3 Cub for tailwheel training in Sheridan, WY (KSHR). Airport 4,000MSL. The aircraft is equipped with a Continental C90-8F engine (200 hrs SMOH) and recent overhauled Stromberg NA-S3 Carb.
Couple questions for you:
Couple questions for you:
- We are unable to find any updated weight & balance info after the aircraft was upgraded from 65HP -> 95HP. One would assume the useful load would increase with additional horsepower correct? I have calls outstanding to Continental for additional assistance but have not heard anything back yet.
- Also, the airplane came with no mixture control and was safety wired "full rich." The ferry pilot's trip from Washington to Wyoming was uneventful and even one our CFI's took a lap around the pattern with no issues on a 50 degree (F) day. The 3rd time we went to fly the plane the CFI reported the engine "sputtered some" during take-off and he turned back to land. After warming up the engine further a second time, he tried again only to have the same thing happen. Does anyone know where to source a mixture control kit compatible with the Stromberg from? A local A&P was able to adjust the carb but we want to have mixture control before summer and significant density altitude. Running into dead ends.
