I have been working on a new-to-me -6A trying to take care of minor squawks since it was delivered in late May. Trying to get ready for a trip to Oakland to visit my sister and brother (who is visiting the US for the first time in 10 years). I am running out of time for this trip and have already missed a previous trip to San Diego and had to go commercial.
ONe of the issues was a leaking carb, MA-4SPA 10-5217, which I disassembled, checked the float (OK) and replaced the needle. Reassembled, turned on booost pump and no leaks. Fired up the engine, went for a test flight, stayed in the pattern, made three landings taxied in. The engine would NOT shut off with the idle mixture cut-off.
I operated the mixture control from the cockpit and the mixture control lever on the carb ran smoothly from stop to stop. I removed the carburetor and float bowl AGAIN. The mixture control is a rotary valve - a tube with a window in it that is covered/uncovered by the semi-circular brass piece connected to the mixture control lever. Is it even possible for the rotating internal part to become misaligned with the window in the tube??
Help I am truly at a loss for what to troubleshoot! Much longer and I will be forced to fly commercial to Oakland (an especially horrible fate when one is 6'4" tall) AGAIN.
