Check my throttle linkage

I have that same carb and one of the first things I did was cut the Ford kick down bracket right off it. I’d read some things about it binding at WOT that I didn’t like and we don’t need it anyway. I did try to bind it up at WOT before I cut it off just to see and sure enough there’s not much clearance at all. I can see how it could happen.
There’s a small return spring hole on the bottom of the throttle bracket near the automatic transmission cable hole mounts. It faces down toward the manifold and can be hard to see but it allows rear return spring mounting. I believe it may show it in the manual but I can’t remember and I can’t reference it right now. I might have a pic but will have to check and get back to you. Acts like you may have lots of return spring tension maybe since everything else seems very free.
