What can be removed from the emissions system on a 91 b2200?

What is needed and what can be removed a tutorial would be nice if anybody Knows of one.

WITH A WEBER CARB & PACESETTER HEADER YOU CAN GET RID OF ALL OF IT LESS THE VAC ADVANCE ON THE DIZZY. READ SOME OF THE OLDER POSTS ON TOPICS LIKE THIS THERE ARE SOME POINTERS HERE & THERE.

I want to remove what i can without getting the weber carb I want to stick with the stock carb. Nikki

THAT IS A TRIAL & ERROR PROCESS, SOMEONE ON HERE HAS DONE IT, & WAS GOING TO POST UP WHAT THEY REMOVED, & WHAT THEY KEPT AS A TUTORIAL, BUT I NEVER SAW WHERE THEY FINISHED IT.....FROM WHAT I UNDERSTAND THEY JUST DON'T RUN RIGHT WITH A STOCK CARB WITH SOME OF THE LINES DISCONNECTED...SORTA LIKE THE OLD ADDAGE... IF IT AIN'T BROKE DON'T FIX IT. IF IT RUNS RIGHT WITH THE STOCK ONE & ALL THE VAC LINES HOOKED UP I'D LEAVE IT ALONE UNLESS YOU WANTED TO DO THE CARB SWAP. SORRY I COULDN'T HELP MORE!
