Default Clutch/Shifting question

Can any mechanics help diagnose this issue?
My '31 coupe doesn't shift right, especially after sitting for long periods. I often can get it into gear after starting the car (gears just grind). I've ended up having to shut it off, put it in gear, and then start it in gear- which usually creates a lurch forward when I hit the starter. It seems to get better a little better as I drive it but not great. What is really odd is that I can downshift (double-clutching) and it works great! No grinding of gears.
Any thoughts? And yes, I'm experienced in shifting model A's and my Tudor shifts great.
Thank you for ideas.

Sound to me like the clutch is not fully dis-engaging. I would try adjusting the clutch pedal adjustment according to procedure, and see if that works. If not, then I would guess the clutch has worn to the point it needs to be replaced.

I am sure others have ideas too.

I'm with Ron, the Clutch is the place to start. Les's book on the adjustment first, if that does not do it, then a clutch inspection is in order.

Change the oil/grease in the transmission. Mod. As need something thick and gooey to shift correctly. Specs call for 600w. That's just a name, not the actual weight of the oil. The actual weight is about 280w. STP has been used successfully and several Lucas products. This is a subject around which a lot of controversy swirls as you will probably soon see. But think thick and gooey and you probably won't be far off the mark.

Thanks-
I should have said that I've also tried adjusting the clutch several times and that isn't solving the problem. I haven't seen cracks in the pedal arm either. I changed the transmission grease too- put in fresh 600 and no better.
So is it possible that a clutch is bad, even though downshifting is smooth and works well?
Thanks!

Open your clutch inspection plate and observe what happens when you depress the clutch, especially the depth to which the fingers and throwout bearing travel. Compare that with how your Tudor looks. If everything looks like it's operating correctly, then it is probably a worn clutch disc.

Some clutches stick if left a long time. Try this: cut a piece of 2x4 to fit between the seat ridge and the clutch pedal. Make it long enough to hold the clutch pedal in while she sits. This will keep it from sticking to the flywheel. jim

I'm guessing the pilot bearing is bad and dragging the input shaft.
