Did you change the condenser in the mag. I had a B with a mag that missed and sputtered, it's under the coil inside the mag. and the kill wire hooks to it from the outside. :
: : I have a '48 Cub that was running fine for years
: : until it decided to sputter and shoot flame from
: : the exhaust. I have traced the problem down to
: : not getting a consistent spark. The firing order
: : should be 1342, when I check the plugs I am only
: : getting fire intermittently, nothing close to the
: : correct firing order.
: When you say, replaced everything in the ignition system do you mean new plug wires? Magneto's demand wire type plug wire not resistor type.
: As far as firing order 1342 is typical as far a 4 cylinders, except for a WD. Roll the engine over to #1 cylinder TDC ready for the start of the power stroke. Get the Magneto ready to fire the pole you want to fire the #1 hole and connect that pole to that plug. When you know which way the magneto roles over connect the next pole of the magneto cap to #3 cylinder then #4 and #2. Somebody may have played a prank on you changing to wires to the wrong holes.
: : I have replaced everything ignition wise except
: : the magneto. The impulse coupling does seem to
: : be working. Could it be a problem with the coil
: : unit? I was always under the assumption that they
: : either worked or didn't, none of this inconsistent
: : spark stuff. Should I disconnect the kill switch for
: : a quick test?
