well, here's whats going on...do i time my motor at idle??? or when should i time it...i think my timing is off big time, but when i go to rev my motor when im looking at it with the timing light, the timing retards quite a bit, like 6 or 8 degrees as i rev it. this is with the vacc. advance unplugged like the timing light tells me to do. is that suppost to happen???? this is new to me and am basically teaching myself...aside from all the tons of help i've been getting from ya'll. also, whats a good baseline to start from???? and can i turn the dizzy while the truck is running, or will it shock the hell out of me???? i remember when i was younger i grabbed a dist. on my dads car and it got me good.
