B&M Converter is bad

Yes. You can check that it is "kick back" by cranking it with the coil wire pulled out and grounded. If it cranks good when hot, with the wire out, you know it's "kicking"

So where is it, 15?

Idle screws. Many guys use a fixed amount like 1/4. I don't I peak them as described, turn them in until I get the SLIGHTEST drop and then back out the tiniest amount. You will get various opinions. Main thing is that it's warmed up.

Your talking the coil wire that goes to the distributor correct? Whats the best way to ground it?

Yes Im at roughly 15.

Ok, I will go and turn them screw in until I get a idle drop then back out somewhere up to a quarter turn. I have to ask again, will that make a big difference in the way it drives or not really noticable
