alright, im trying to set my timing but i think the last owner f*cked with it already. on the balancer (or whatever that thing with the timing marks is called) it reads from 30* retarted to 30* advanced. next to one of the lines #'d 30 says ATC and the other side says BTC. what the hell does atc and btc stand for?
which way do i turn the distributor for advance and which way is retard?

with my mods, what is the optimal setting?

rigth is adv. and 12-14 is always best.
