Thats really weird Gary. What do you have for a motor? Did you go with champions instead? Ive seen it before where the plugs electrodes were too close to the pistons or too far away, indicating the wrong application.

I had BUZ8H in the motor which are a supressor plug(20$ a shot) so I tried the non supressor BU8H (4$ a shot) didn't run nearly as good
