It's sluggish beacuse it's a 85 diplomat. I ain't trying to get it any better. Just ripping out the lean burn and going to gm ignition while I'm at it

Got ya. If you did not know the dist. in it with the lean burn is locked out so you have to get a non lean burn one for it along with a different carb.
