Have a 200 merc blackmax with wh-28 carbs. Running .80 and .82 main fuel jets. Can anyone tell me what size the idle jets should be or what kind of ratio to use to figure it out?

Thanks transomstand. My manual had .56's with the 74 jets but no info on the .80's and I definitely do not want to be to lean. Thanks again
