Happy New Year!!
Confused... Am I doing something wrong? Bad mag?
In the middle of my condition inspection, checked mag timing and found that right mag is perfect at 25 deg BDC, but left mag points only open after impulse coupler drops at TDC.
I am not the builder but do my maintenance under supervision of A&P. He just left town for two weeks so wondering if I can figure this out sooner than later.
Background:
We (A&P and I) timed the mags a couple of months ago, both perfectly 25 BDC and in sync. No problems since then (until now), both mags checked OK at run-up. Using induction type buzz-box for timing. Tried rotating the mag by hand in case it had loosened, but it seems tight.
Did notice couple of drops of oil at lower case mounting bolt, can't tell origin, assumed it was from recent timing when mounts were loosed and re-tightened during recent timing.
Have tried all switch positions (L,R, both) to no avail. 0-360-A1A, Slick mags.
Thanks in advance for any help.
