Also, if you haven't yet, get an NGK plug to replace the stock one.
As for making one last longer?
Never wore one out, yet.
Actually I don't think my motor has a primer button. Also, it started up pretty quickly today. I just hope it stays that way...
As for longer, I'm just deathly paranoid. I know of a friend who had a motor that lasted a few short months. He would leave it out in the rain and ride it for extended periods without tightening up the nuts. He basically didn't know what he was doing. I just want to avoid as much subtle, newbish behavior that that might not be completely obvious to a new owner.
