Edelbrock stubbornly runs rich
Not too sure what i'm doing wrong here.. i'm kind of a newbie to carbs.
The car is an '86 former TPI car converted to carb. It's got an airtex electric fuel pump for carbs, 5-9psi, 30gph with a holley regulator set to 5.5psi
The carb is an edelbrock 1407 - 750cfm, on a 355 w/ sportsman II's and a hot cam
no matter what I do the car runs rich, the plugs get black after 10 minutes. timing is set to 34 degrees total timing.. when i took the top off to check the floats there was this brown slimy stuff on the bottom.. that's getting cleaned out
idle adjustments dont really do much it just puffs out smoke.. any ideas?

Re: Edelbrock stubbornly runs rich
Well... changing jets will change the air/fuel ratio. Although I admit, it sounds like you tried that already.
