I can't get the full rpm's. Slushish out of the hole. It has a slight
ting. The distrubutor will twist back & forth when the distrubutor hold
down bolt is loosened. I've tried a few different settings and it does seem
to effect performance, so doesn't this mean that it's adjustable?

Sounds to me as if the knock sensor or the computer itself is bad. I'd
get it diagnosed.
