How do you do it? I have read that it can be done, but would like to know what I need to do. Also, what other changes should be made to these carbs? I know they were good already, but there must be improvements that can be made. It will be going on my 66 stang.

Two different ways. The simplest is to make it one to one via a bent piece of linkage and a new hole in the secondary bell crank on the passenger side. I don;t like to do them that way for S&S or strip(competition) only cars. I prefer to use a progressive secondary linkage bar that is no longer in production. I duplicate them as does Pony Carb. That is the BEST system as it allows you to drive around primarily on the primaries. (that's a mouthful )

So do you sell the linkage pieces that I need, Alex? And, of course, if so, how much? What else would you reccomend I do? Ditch the power valve? Change the jets? Or just tune it for what the car likes?

I do not sell the parts Kyle. Sorry.
I only sell them with a competition carb prep. ($550 exhange) Maybe Pony sells them individually???
I definatly remove the power valve on any performance Autolite build up. I only leave them in when I leave them vaccum secondary and that would be for a near stock engine.
Jetting will be trial and error, but a medium hot motor with a 1.12 usually likes to start about 54-58 or so.

Would it be possible to modify parts from a holley double pumper to work for this? I have the base plate from an 850 spread boar double pumper that I can steal off of. I know the shafts won't interchange (obviously) but can I use the attaching pieces? Should I just try it and find out? I emailed Pony Carbs to see if they have what I need. I'm using this carb on the mustang untill I get a twin turbo car together, when I will use it on there. Thats why I want it to be a mech. secondary. Maybe it would be easier for me to sell the 4100 and get a Holley 4010 double pumper?

Nope, almost no Holley parts will interchange with any Autolite. Only the power valves or pv plugs.
