Hey all, wow been a while since Ive been on here. Problem when I take my 73 750 with a 1970 836 engine out for a ride. it runs great for the first hour or so, then it starts sputtering and missing only on acceleation. I have the dyna s ignition on it, been running that for years. wondering is one of the coils heating up and messing with me, is it my dyna s I am baffled. help me please Craig in Maine
