I've been out of the game for awhile but warm weather is coming so I want to get running again.

I've seen a few posts where people have used washers to shim the needles for their carbs but not really a how to, what to use, or a why.

Before winter we had her running but only at about half. It seemed like one and three ran hot while 2 and four just kind of sputtered along.
