I'm running 2 Holley 4777-4 carbs. I need to see a exploded view (online). I think these are 650's (4150 model). The rebuild kit I have shows view for what looks like a 660. Hopefully I can find an exact blowup of my carbs. Anyone know where to see the diagram ? I think I got something put back wrong in one of the carbs as it has problems.
