Maybe; hard to tell just where it might go. Remember I told you the 
throttle-shaft 0-ring seals we used were to seal for blow-thru supercharging. 
But there's still the unmetered air being sucked in thru the oval throttle 
shaft holes, that screws with  good mixture control. This may be why the 
thing ran decently with those big secondary jets? If you're absolutely in 
love with that particular Holley, try locating another Holley of similar size 
& swap the throttle castings. It need not be the exact same carb to fit. The 
San Jose Flea Market used to have a "Mr Carb" where you could get parted-out 
Holleys & other brands. Cheers- J DeRyke
