  1. Backfire/startup Problems on a 68' with 454

    Drivetrain & Performance
    Need some help on which direction to go because when cranking up the engine it backfires bad. Just installed brand new spark plugs but when i checked them they are completely saturated with gas. Could it be a bad carburetor (Holly 750)? Worried about firing it up again because of the backfiring...
