i noticed that when i pulled off the spark plug boot once there was a little rubber peice on the spark plug, so i threw it on my work station and put the boot back on, no isues., isint the resistor gold inside the cap? im not to worried about taking it out, but the plug was 4 dollars and it said to improve HP gain so i figured what the hell, im taking the governor out and putting new oil in it, why not give it a new plug.(also good for a plug chop) and i may just get the one for gx200 later, but ive never done rings on one of thesse. i also thought about a gx140 E tube but im not going that far just yet. lets see what i get from all the mods im doing right now
