Thanks Hal,

That's exactly what I'm doing right now, but it seems like it should have loosened up by now. I've been spraying PB Blaster onto the stem and squirting oil also, but to no avail yet.

For now, I guess I'll keep trying the oil and see if it comes around.

Paul,

Thanks for the tip. I must admit, though, I've never heard of Liquid Film. Where would I get some of that? I'm open to any and all suggestions.

Some lubri-plate may help. If you have the head off I would pull the valve and take a look at it.
The stem may be rusted from water. Hal

Thanks Hal,

Unfortunately, it's a flat head engine. To remove the valve, I'd have to pull the cylinder off the block to get access to the valve spring keeper.

If I can't get it loosened up with lubicant, it looks like I'll have to that.

Quoting Removed, click Modern View to see

IIRC there's a cover that you can open to adjust the valves. Richards Lawn and Garden is the big source for old Gravely stuff in the US. There are a couple of Gravely clubs on line. I'll see if I can remember to find the shop manual and take a look for you.
