3/4 turn on both ought to get it going. An interesting thing on that type carb is the slow speed needle screws IN to make it richer—-backwards from most carbs. Having said that, a FEW motors put left hand threads on the needle to correct for the backwards-ness. Not sure if this is one of those or not.
Thanks Frank, will give it a try. Gave up on it last fall would not stay running. Just stripped the carb again found nothing out of sorts. Tank is rebuilt. Will give it another try. jr
