I took measurements and I think the JBM M-73 diaphragms should fit my carb, though it seems all the old posts mentioning this were people with 80s XS models and the JBM site mentions 80 and newer.

I am trying to button up my cleaned/rebuilt carbs and it's just seems they shrunk too much to get back in place. They are a few mm too small so I have to replace them.

Also not trying to buy unknown ones off eBay for $60 or more and waste my money.

Opinions?
