CAJUN YJ Yea. Def have to set the vac adv. no as far as setting it, that takes a lil time. Kinda have to play with it to get it right. Took me a while to set mine.

CAJUN YJ Yea I would def say running too rich. My opinion, fine tune carb an ck ur timing again. Have you set your vacuum adv on ur dizzy? That will affect your air/fuel mix too.

Billmummey It's a constant puff of black... Not to dark but if you hit the gas it does get darker and of course more comes out until it cleans itself back out

CAJUN YJ You r running rich. Black smoke is better than white smoke. A lil puff of black smoke won't hurt. But if it's a lot, I would try re set ur carb. If its bad an you leave it, your gas milage will b bad an you will foul plugs.
IMO, I would advance your timing just a lil bit more.

Billmummey Black smoke so I turned the dizzy and it turned a little blue and smelted strong.... It ran bad before the upgrade so we messed with the carb to try and compensate for it and I timed it by sound, when it ran smooth I called it good.... Runs great where I set it now just black smoke puffin out and especially when I hit the gas... Never did this before the dizzy upgrade

Did the HEI dizzy upgrade now it smokes

Any reason why my 4.2 smokes now could it be timing or is it most likely the weber being out of adjustment?
