Engine Sprocket Replace

[perkoff]

My chain jammed up and I lost two teeth on my engine sprocket, I removed the sprocket, I was just wondering how to put it back on?

the opposite of taking it off,,,
make sure the key it set correctly
when it is tightened completely, give the wrench/ratchet a quick little rap with a hammer,,,it will want to come loose again...happened to me once
