    Has to be the plug caps, wires, or plugs. The coils fire two plugs: 1-4 fire together and 2-3 fire together. If you're missing on 3-4, to me...it suggests caps or wires. Have you switched things around to see if the problems follow the switch?

      is it possiable that it could be the conectors down on the side of the motor where you set the top dead center for the crank cuase im getting fire on 3 and 4 but not 1 and 2

        Sorry...I misread your post. However, the same logic applies. YES, check to see that all connections are clean and if you have a tube of dielectric grease, use it. I repeat, clean all your connectionss first...then if you still have no spark on 1-2, pull the plug boot off and trim back 3/4" on the wire and reinstall the plug cap.
