when the rod is longest and the valve is closed like you talked about, is that because of that little sensor that the pedal rests on? when i take the master off of the pedal the valve is open, so i assume that closed valve is because you are supposed to adjust where the pedal rests until it pushes the pedal enough to where the valve closes, and then turn the rod side once or twice to open the valve again? well I tried that and I still am having the same problem, if i've done it all correctly the only thing that I can think is I have a TOB issue or a bent clutch fork (which I don't think its either one of those I think its an adjustment issue)I made a mistake with this advice. I meant that you should adjust the rod longer until the slave stops pushing in. Then you shorten it one to two turns so that you can push back on the slave to return fluid back to the master reservoir.
Essentially you have a variable one way valve in the master cylinder. You want to adjust that master cylinder rod so that the valving allows flow back to the master reservoir with the pedal all the way up in it's resting position. You may have to lift the pedal by hand or foot to it's resting position if the clutch isn't resetting it's position for you. You want the valving the block that flow with about 0.125-0.25" of pedal travel so that pressure builds to disengage the clutch when fully pressed to the floor. If the master rod adjusted too long, the valving will block flow back to the master reservoir at the pedals resting position preventing clutch engagement when the pedal is released. Then if it's adjusted too short it may build pressure too late in the pedal travel to be effective enough to disengage the clutch. There is a fine line of adjustment where it needs to be to function properly.
You don't want to press on the clutch pedal while you are doing the procedure from the video for the final adjustment. What I proposed is as a simple test to see if you have a point at all in the pedal travel where the master valving prevents you from pushing the slave rod in. IE if the master rod is adjusted to the shortest or longest and you can still push the slave rod in... then have someone softly press on the clutch pedal until the valving in the master prevents you from pushing on the slave rod in. If the distance you have to push the pedal is significant like 50% pedal travel, there is no amount of adjusting the master rod that will fix this and you should look into obtaining another master as a last resort.
