400AT Jetting questions and valve clearence

A friend of mine has jetted his 400 rancher. I believe he has only put an air filter on. We need to make some adjustments to the air/fuel mix screw. How many turns is everyone doing on there's? He doesn't have an exhaust yet. Also we need to do a valve adjustment, what;s the clearence on those? Thanks!

.006" for the valves.The sight plug is hard to see into on the 400at so take your time to make sure it's at TDC.
start at 2 1/2 turns out on the screw but you may have to go more (unscrew)if you get any backfires on deceleration.
