Ignition Question

[dblanton]

Does anyone have any suggestions as to why when the plug wire on #1 cylinder is pulled while the engine is idling the rpm would increase; pulled on #2 little or no change in rpm, pulled on #3 engines dies?
Each plug wire was placed back on the spark plug before pulling the next one.
I have checked the position of the spark plug wires and they are correct, (the plug wire on #1 coil is connected to #1 cylinder, #2 coil to #2 cylinder and #3 coli to #3 cylinder. I have checked the position of the primary coil wires and all three coils are correct according to the wiring diagram in the manual.

change you heading, or new post "RPM's increase with plug wire off" may get more attention. i have no idea, never heard of it.

Probably preignition. Test the ignition coils according to your manual.A bad coil may have damaged the powerpack, but if you replace the pack without knowing and fixing what damaged it, it will just happen again.

Look under the flywheel for any dripping material. Has anyone had the flywheel off since the motor was last running well?
