Help, I'm confused.
I'm told that you should hear the impulse mag click at TDC. Mine occurs 5 ring gear teeth past TDC (approx 12.5 degrees on 142 tooth ring gear) should I ad just? I can move mag to click at that point but then the timing light buzzer indicates at about 37 degrees before TDC instead of 25. This is new factory engine from Van's and I've flown for 132 tach hours over the first year. Starting became problematic. I'm doing condition inspection now using E 50 mag timing buzz box. Plugs looked fine. Filter quite dirty. Plug gaps .022 (range .016-.021).
I'm hoping just cleaning the filter and plugs and adjusting gap will result in easier starting. Also mag sync was off some and I fixed that. Just wondering why that coupling clicks when it does and if I need to do something with it.
Thanks!!
