Low compression

I found this for grinding seats in the block. Neat how the pilot locates in the guide bore and the lifter bore. I guess this is what you have?

I'm still curious about refacing the valves. The refacing tools I have seen look like this, with a collet chuck holding the stem. How is the flattie valve held with the mushroomed tip?

Open the collet further, slip the valve in, and tighten the collet on the straight part of the valve stem.

The valve grinder puts the stem against the side edge of the stone.

Yes, the valve grind kit I have is essentially the same (mine is snap-on) as that shown in the you-tube video. Their guide tool is a bit more specialized than the ones I have, but certainly a good idea to get the valve seat bore aligned to the lifter. I take exception to them describing the tools as obsolete or antique. Those are what I learned on.

Ouch. Touched a nerve, did it?
