I'm not exactly an idiot, but these are the stupid little things that will get me in trouble. These plugs did make a world of difference. I am going to guess because the plugs I took out were the same plugs that I installed when I rebuild the motor last season. I have done a LOT of tuning since then, including a complete carb rebuild. So they were probably pretty bad, I just didnt realize it. I will switch back to The correct size and hopefully it will have the same effect.
