How many turns open on the H & L screws to start on a 670?

Most Tilly's wind up at 1 1/4 out on Low, 3/4 out on High, providing everything has been checked out. But like Eric said, 1 1/2 out on Low and 1 out on High is a great place to start before you lean it down a bit.....if you have to turn in more than 3/4 on High to get a decent 4stroke, something is wrong like a seal leak.
