    How do you lap valves?

    I tried using the standard tool, but I felt awkward trying to use it... sort of like a cub bear trying to screw a football. So I used a standard valve stem from a wheel and chucked it into my drill. It was just fine at first, but then it got a little loose, so I put a hose clamp around it and tightened it up just enough to give it a good grip on the valve stem. Over the course of twelve valves I tightened it a couple more times. I turned the valve on the slowest speed, and after a second of grinding, I would push it in with the drill, and then push it back onto the seat with my finger. That seemed to pull more compound back into play.

    looks like it works... I use a piece of fuel hose, and always have one hand free to slap that bugger against the seat.
