WTF does spark plug chop mean?

short verision...... warm machine up on a old plug, once warm, swap in a new plug, than proceed to make a wide open pass thre 4-5-6th if can, than once you let off the throttle shut if off, and pull the plug. than cut the threads off the plug to see what color the porclen is...

you want golden toast color



search engine section for in depth directions
 
you dont really need to cut the threads off

true.. im just sayin whats posted everywhere... hell me personnaly iv NEVER done a plug chop.. i guess its the car guy in me, i set it up my ear and responce.. everyone seen vids of my old blaster... no hesitation anywhere!!! no pinh no detonation, no fouled plugs, started 1st kick every time in the middle of winter and warm weather
 
not to step on feet here being new, but if you research plug chop there is a band of color at the base of the porclen not visible w/o cutting the plug this is where to actually look


please no power band jokes
