Yes, that is clear. Thank you. And that's how I assumed they worked. The way you said it before made it sound like there was a bypass built in. Anyway, what you said in the last post makes perfect sense.
Based on the operation of the bucket cylinder fully extended or retracted, and the fact that it won't hold the curl/uncurl by itself, and that it "popped" a couple of times where the sound was coming most certainly from the cylinder, I think that pretty much proves there is a leak in my mind. I almost liken the sound to if you have one of those rubber poppers that you flip, set on the ground and then they flip back and bounce off the ground. It almost sounded like that. I could do your test and mess with the fluid, or I could just open it up and inspect it.
Which begs another question, let's say I was totally wrong and the problem wasn't in the cylinder at all. Is just the act of opening the cylinder and taking the rod out require that all the seals be replaced or can the old ones remain? And, what if it just that one of the seals rolled off (however it may do that, I don't know). Does that seal or all the seals need to be replaced, or can it just be reset?
Thanks again for all your answers, I really appreciate the advice!
