Re: can't ignite

ok i've got another coupling for the CC that has a hole drilled in it and a filed down nut welded over that to keep the spark plug in place (it was on in the first 2 pictures i uploaded). I can put it back on the CC, but the spark plug is rather small; CJ8 (came off an old weed eater). Will a weed w...
