My clutch petal has gotten a little sticky. When I come all the way off, from a shift, it holds for a second, then pops down to its resting position. Doesn't affect shifting at all, but the noise it makes is really getting on my nerves. What kind of grease/lubricant should I use on it, and will I be able to fix it from the cockpit, or do we think I'll have to delve a little deeper to solve the problem?

 

Bleed the clutch cylinder, that might help.
