holley carbs

Ya can't make a Carter a full mechanical secondary carb. The closest you can come to that would be (on an AVS) to remove all tension from the air valve spring or (on an AFB) break down the carb, remove the air valve assembly and remove weight from, or entirely remove the counterweight(s)


The throttle plate opertaion can allways be made to operate. You just need to remove or modify, aka cut off a tang, in order for the secondarys to allways open up.

Do not remove the counter weighted secondary door and reassemble the carb without it. Just incase you misread/understand what 68 means. Just remove enuff weight till it stays open. (Not a great idea IMO, but if your car can handle it, then by all means........)

As far as getting a secondary squirter to work, check out this shot of a modified AFB.

Note the secondary squirters and the adjustable rod set up.
Owner of the carb told me the rod was modified to a long slope rather than a step rod. Then straightened and threaded with jam nut, locking nut.

He didn't say how he ran the plumbing for the secondary squirter, but I poked around a few carbs I have. I think it easier to run it external rather than through the carb.

No word on the air horn.
