I've got my main gear "T"ed together from a Robart variable rate valve. The Right gear always goes up (and down) before the left one....there is probably a 5 -6 second delay between the two. They both work reliably every time, but I'd like them to go up and down more or less together. I thought maybe the left was was a bit tighter, but I have cycled them probably 50 times now, and no change in that behavior.

Any suggestions?
