Hi. I bought a Holley 4160 600 cfm carb last year, and I'm having trouble setting it up. I had 8 gallons of gas in the car when I changed the carb from a 600 Edelbrock over to a 600 Holley. My problem is I think it may be running way too rich. It seems to go through a lot of gas, and the fumes, and smoke in the garage is really hard on the eyes. Could this be the problem? And how do I fix it? Thanks.
