hey everyone, wanted to ask for some advice here. i've never seen anything like this before:
my '52 N all of a sudden went from running perfectly well, to missing under load, idle, & all throttle settings. after double checking everything from fuel to point gap, i found that unplugging the coil wire from the coil & holding it about 2mm above the coil contact while running (so blue sparks are visible) solves the issue. fully seating the coil wire causes the miss to come back.
what does this mean? seems like the extra gap the spark travels from coil to wire fixes the miss/ rough running. i'm stumped here. i've swapped in a new coil, same issue. new coil wire, new cap, condenser and plugs give same result. checked and rechecked point gap @ .025 all 4 lobes. as soon as the coil wire is seated fully into the coil, it returns to running rough. running blue streak/ standard ignition components. 12v, 3 wire alt. zenith carb. sidemount dist. AL437's at .025
what is going on here? appreciate the input and all the past help i've received by searching this forum.
