Ok, I am going to guess here a bit. as load increases, the engine sputters more... if I was to KISS this thing, I would be looking at firing order. it is TOO easy to cross 3-4 or 1-2 in the order. start there. then look and check for weak or off brand plugs. I am an NGK guy. have then in everything. Learned my lesson on my 8N front mount. won't run on anything but champions. go figure. then, it is flat a weak spark? next KISS would be to verify 6v + in the battery off, and at idle. next thing in line in my estimation is the capacitor. have seen far to many of these recently be bad out of the box. Next Kiss I think is to verify point gap. if Dwell time is not open long enough, weak spark becomes the issue. check the point gap, and if you are on the small side, try going to the large side.

Next question, have you verified compression? just off my nut thinking here, but low compression would show thew same as weak spark.... Baahhh... my two pennies, about all its worth. hope I helped, maybe I triggered a memory or idea... good luck !
