I have a pro billet dist and was wondering if I read 15* at idle can the dist be wrong and it not really be at 15*. I ask this because as some of you know I'm trying to find a idle miss and Just checked my timing again and I'm at 15* inital and 45* total at 3000rpm?? When I set this up I set it up at 36* total. I guess the springs could strech or something I suppose. I'm trying to find out If my prob is the dist. The reason I ask is I did the pull one plug when it was running trick. When I do that they all sound the same! Could the whole dizzy be off and making it run weird? No matter how I turn it it still runs the same. I'm also using a dial back light. MSD says not to use one so who knows. I know I need to find another dizzy , but nobody I know has one. I'd love to eliminate all the ignition.
