i bought a used 1986 honda accord carburated.i decided too do some maintenance on it and put some new sparkplugs in it.2 came out ok while the other decided too be stuck while trying too get it out.i eventually got them out and when i tryed too put the new ones in there werent going in.i eventually got the 3 new ones and the one old one back in too the same place.the only thing iam wondering is it going too be ok that the one plug hole i had too stick the old sparkplug in,its in only about 3/4 of the way?i tried too tighten it as much as i could without ripping the threads off.

also,how hard would it be too helicoil the plugs so it will go in like normal?thanks
