Ok guys.. I know I should have this figured out by now, but after getting the timing of the mag 180 off on the 1947 M, and doing the same exact thing on the 1942 H (prior to the issue I just had).. I have to ask before I put this mag back on the H to fire it (I did get it running by the way for a short 15 minutes - see attached video)....
What position should the rotor be pointing to be ready to fire on #1. I have enclosed pictures of how I had it set up the last time I installed it, and it was 180 out. I had the impulse set to begin to reload the spring with the rotor pointing at the #1 terminal as you see in the photo.
Thing is, the mag seems to fire on #1 with every-other impulse trip when I have it clamped in my vice, but when I do this on the kitchen table, it only fires every 4th trip.. And I think this is what is [possibly] throwing me off. Check out the photos and let me know what you think. First photo is of the impulse coupling at the beginning of spring preload. Second photo is of the rotor pointing to #1 prior to tripping it to fire. This should be right, according to my brain! Bolt it on at #1 TDC... Should be good to go (I swear I try this every time, LOL). I must be doing something to mess this up, somehow.
Thanks for the help, and hopefully tomorrow or Friday when I get to reinstalling it, it will be for the last time, and I'll have mastered these H4's.
