Replacement YF

[Anonymous]

Hey guys,

I am doing a total tune up of my maverick(head gasket, new carb, heater hoses, all of it!) and just got my replacement carb from kragen. My original carb when I bought the car was a holley 1940, and I had no luck at Kragen getting a rebuild kit for it so I went with ordering a new rebuilt one. What I got was a carter YF with the correct adapater plate and everything so it will bolt up fine. My question is, I have the dual advance distributer (two vacuum lines going to it!) and my replacemnt carb only has one vacuum port as opposed to the holleys 2. Am I going to have to get the single andvance distributer or can I just plug on of the ports on my current one? The id # on the carter is 64-1084 and the vacuum connection is in the adapter plate between the carb and head.

Any thing else I should check before I bolt this carb on?

Thanks for any replies

Mike, sounds like you have your hose connections backwards. The outer diaphram on your distributor advance canister should run to ported vacuum on your YF (not constant manifold vacuum). This is what gives you timing adavnce. The inner port on the advance canister is what is supposed to run manifold vacuum. It retards the timing when not under a load. I would just plug it, but you can hook it up and see how it runs.

8) What was the part number they had listed for the carb you got?

I believe the number was 64-1084 or 104906-0851. I just got my head back on and went to bolt up the carb and its the small hole (1.5 inch) opening on the carb adapter. Grrr, looks like I might have to modify it to fit. Also, instead of pulling down on the throttle plate, you must push up on it for it to open, this is beginning to turn into a custom thing! I miss my holley 1940!
