Are you absolutely certain the magneto is properly timed to the engine? From your explanation it doesn"t sound like it would be.
Take out the #1 spark plug, turn the engine over until #1 comes up on compression. The impluse on the magneto should trip at or just after top dead center as determined by the "center" timing mark (the magneto will automatically advance the spark once the engine starts). Stop at the point where the impluse trips, and take the distributor cap off the magneto. The rotor should be pointing at the position for the #1 cylinder. You can repeat the process for the other three cylinders if you want to verify that the wires are in the right order.
If the impluse doesn"t trip at or a little after TDC, or the rotor is pointing to the wrong cylinder, remove the magneto, turn the gear until the rotor points in the right direction, and re-install it. Repeat the above check for fire at or just after TDC on number one. You may then have to adjust one or two teeth to make the impulse trip at the right time. Fine adjustments are made by loosening the bolts through the mounting slots and rotating thewhole magneto a little bit.
Don"t set the magneto to make the impulse trip at the "spark" mark...that"s where its supposed to fire when its running, and the magneto will automatically advance the spark when the engine comes up to speed (actually, the impulse mechanism retards the spark for cranking). If you set the magneto timing too early, the engine will kick back & break your arm if you"re cranking, or do all sorts of nasty things to the starter if it"s got electric start.
