With 3-piston engine is running,

With 3-piston engine is running,
I installed 4 plug Champions RA8HC parks instead of NGK DR8. I burned the NGK when the engine was cold. With the Champion, it's okay. There are current on spark plug but the engine is running on 3 pistons. The manifold of the piston is cold and defective spark plug is wet. What is the problem??

I would guess that when you installed the new plugs you pulled a plug wire loose from the plug cap. The wires screw onto the plug cap. I would pull all of the wires cut about 1/4 inch off of the end and then screw them back on. You may even have to clean the screw that is in the plug cap before replacing.
