My 1940 BC65 was in storage for 2 years, and when I recently fired her up a month ago, I gave her six blades to prime her, about an eighth of an inch of throttle, one handed the prop, and she fired right up. I taxied her over to the FBO, where my sweetie Pie and I switched the Bungees, (that tool that I got from a fellow member made it SO easy, I felt like I was cheating).
After that, we installed new tires on the main gear, and pulled and packed the main gear bearings, while our friend and A&P checked our compression, and it was between 65 and 67 PSI, with the timing dead on.
The last thing that we did was change the oil, and then went to fire it up.
The engine that fired up on the first pull cold, took six or seven tries to fire up when warm, and it has never done that before. Once fired up, she ran fine, 50 RPM drop on each mag, max static was 2100 RPM.
A week ago, I went to fire her up, and did everything the same as I always have, she tried to start on the second, third and fourth tries, but she kicked BACKWARDS for two blades each time, (I still have ALL my fingers), but on the fifth shot, she fired right up perfectly. I chained her tail wheel and everything was perfect. I then went to the FBO and asked them if it was possible to have broken an impulse coupling on one of the mags, causing one of the mags to fire too soon, causing the engine to kick back.
I then asked if I found out which mag was still clicking, and then started on THAT one, switching to both when it was running. They then told me that only one mag HAD a coupling, and I should start it on the Impulse coupled mag, and then go to both. I told them that I had always started it on both mags, and never had any problems, but I'll do what it takes. WHICH mag has the impulse coupling? I think that they said it was the left, but I don't remember.
