Thanks for posting that. I've been gonna replace the Roch. B on my 292 with a YF Carter for some time now, this'll hurry me up on it. Getting a bit over 18 MPG in my '55 Bel Air on road trips now, what got me started was I can't find Roch. jets & I learned that YF's use the same as AFB jets, I've got a bucket of those, sure wish the met. rods were the same.
