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. ------------------
