Make sure everything is nice and clean. Replace the o-rings on the diaphragm and lever body, then reassemble. You should now have a clean, leak-free petcock. The kit comes with a new o-ring for the petcock-to-gas tank connection as well.

You should probably change your oil now, before you start it up. If the petcock has been leaking into the oil, not only will you have too much oil, what's in there will be thinned out and much less effective. You don't want to replace major engine components just because of that.
