One more question. Having been inside there, you know that the 'dog bone'/connecting rod has no hard connection to the piston, so if after you are lifting the arms manually, it holds in the up position, then some fluid was pumped into the cylinder. So the only other way the arms would stay up is friction in the rockshaft bushings. If this were the case, lowering the touch control lever would not cause the arms to lower. Finally, the question: does moving the touch control lever to lower actually cause the arms to drop?
