Question Uneven Holley fuel distribution?
From the appearance of the spark plugs in my recently built 351 Windsor engine, it appears that plugs 1-4 are getting considerably more fuel than plugs 5-8. I'm running a 650 CFM Holley 4150 (double pumper) with no choke on a RPM Performer Dual Plane intake manifold. The carb was on the car when I bought it, so other than jet size and power valve, I have no idea how it is set up. How can I tell if the carb is providing more fuel to one side than the other? What parts of the carb are most likely to account for uneven fuel distribution? Any other suggestions for troubleshooting this problem?
