Does anybody know the exact size of the pilot screw oring on trx300ex 2002?
Just rebuilt carb but somehow lost oring.
Dont want to buy another rebuild kit.

I would just take your pilot screw to your local hardware store and find a tiny o-ring that fits snug around it.

Yeah, that would work or you could probably get one at the Honda dealer. They might not have it in stock, though.
