Rebuilt the carb, everything is set. but I start it up, and it pins the throttle, I can choke it off a bit, but it seems like the idle is super hiugh, except I don't really have an idle set screw. How do i set this damn thing "properly"!!!!!
Anyone know of any online info? or anything more then the exploded view I have on paper about these carbs.
It's a ford carb, with a C4AFM tag on it.
 
I am not familiar with your exact carb, but surely a 64 model had an idle speed adjusting screw? Double check to be certain that the throttle plate is closing all the way, and also that the linkage isn't holding the throttle slightly open. A vacuum leak with too rich fuel mixture can cause high idle, is the vacuum advance hooked up properly and functioning as advertised? Too much advance will speed up the idle also.

On my '62 I set the idle where the throttle cable connects into the carb.. a nut and a thumb screw. If my fuel mixture is too rich, my idle runs crazy high.. It will also do that if my intake manifold has worked loose, which seems to happen every 18 months or so. I find myself taking a torque wrench over the manifold bolts when I do brakes (once a year or so)

i have a 1bbl carb with manual choke that is a motorcraft. . i am thinking yours is probably an electric choke, so it might be different but try this. take the air cleaner off and stand facing the motor from the drivers side. at the back of the carb,wher the choke arm is, there should be a 5/16 screw that bnutts up against the choke arm. that is where the idle is adjusted. i am unsure about the electric choke models but maybe this might be helpfull in your idle problem.
