shifting shuts my car off

I know its a one barrell carb, i dont see any helpful markings on it, alot of markings but nothing helpful.

I have adjusted the screws a little bit, but since im fairly new to workin on carbs, im not really sure what i am doin, i know fast idle is set pretty darn high. the only other carb ive adjusted was a Carter RBS and that was super simple.

and yah ill take pictures of the engine bay when i get home from work.
