I am just about to begin the conversion of my tri power carbs to three Autolite 1100's. I was able to find a hellish crummy (but complete) old Falcon 1100 with a hand choke and dashpot for automatic tranny. I have decided to use it as the center carb. I like the way the base is cast to fit the hand choke stuff correctly to it without having to 'mush fake' anything. I rebuilt it myself. The other two are nice 1100,s without dash pots that I have rebuilt and modified for the outer carbs. All three have 1.20" venturies. The center carb has a 69 stamped on the jet, the two outers have 64. For those who don't already know, this tripower is installed on a cammed up 200 CID with the works.
Here's question 1: I noticed that the Falcon carb throttle plate is almost a quarter of an inch larger diameter than the other one. I remember 'El Pajarito' telling us about how he got a remanufactured Motorcraft 1940 with the same size plate problem. Anyhow, this carb will still open OK sitting on the OEM carb spacer. However, it leaves an exposed edge all around the base since the spacer hole is smaller than the carb hole. This is true not only with my existing carb spacer, but also with the spacer that was on the Falcon! Should the spacer be beveled to create a smooth transition between the two, or won't that matter?
My current center carb is a Pony rebuild. I plan to take the the top half off of it and put put it on a non dash pot lower half and use it as an outer carb.
Question 2: will the Pony modifications they do render that carb incompatible with non Pony rebuilds? Are the Pony upgrades done to the upper half, lower half, or both?
I am currently gathering fuel lines and fittings and should be able to start the conversion next week.
Oh, one more thing, I will also run the dizzy to manifold vac during this mod. I have ran it to the SCV now for more than 3000 miles. It seems to work OK, but this way I will find out if Bort 62 and others are right about the manifold vac vs. SCV issue. If it does make a difference we will find out then!
