Professional Products Crosswind Intake Manifold

Vacuum read a little on the low side. Around 19psi which isn't terribly low but lower than I'd like. Just a little bounce in the needle, less then half a pound in either direction.
I tried hooking up my timing light noticed my crank pully is to dirty to see a timing mark. I'll clean it up and try again.
My choke was stuck closed and it's running a bit better now. Less black smoke although not entirely, think I noticed some blue smoke under the black smoke so I'll have to look into that. Tomorrow I'll check compression.
