Small block question

I’m asking for advice and anything you guys are willing to share, I will take and leave nothing. I’ll look into the linkage, thank you for offering your advice! The trans is the only thing not worked so I’m expecting it won’t last. What would you recommend?
The throttle linkage suggestion is actually a great thing to follow up on. I have seen a BUNCH of instances where people were wondering why they were not getting the performance they expected. Well, then the carb doesn't open up all the way.......
Also, I really appreciate your great attitude. Sometimes people ask questions and get irritated when members point out other things. You will get along great on this site.
