BST 40mm valve spring

[phillip]

My lil lad found my box of carbs I had took apart for cleaning. And took a valve spring to play like a slinky doh  smiley-shocked003 So here the question can I use a valve spring from another set of carbs like 36s or something or if anybody breaking a set of 40mm carbs let me known buy the spring of u. Thanks for any help

Compare them, I dont see why not if them are the same size, them are only to push the slide down
