Post subject:  Motor running off one cylinder

I have a 23hp Briggs and it’s only running off one cylinder. I took the spark plug out, it is getting fuel and a spark, but motor still bogs down under load. Just wondering if maybe it’s the coils or something. Replaced the plug the same day and ran the motor for about 15 minutes, and it already seemed to have fouled the plug. Anything helps!!!

Check ur intake gaskets. One of my intake gaskets blowed out and it killed the cylinder.

Remove the kill wires from the coils (motor will have to be choked to turn it off), If it runs fine with the coils unplugged you have a bad diode. More than likely killing one cylinder.
