Hello all,
My wife and I recently bought a 1956 ranch home, complete with the "Cadillac of toilets," a Case 1000 lowboy. I purchased a complete replacement part kit, and after quite a bit of work, got everything installed and functioning. Let me say that while moderately handy, I am completely green at plumbing - let alone 60+ year old plumbing. I also freely admit that my biggest mistake was throwing away all of the original parts before troubleshooting to see about replacing only what I needed to - this lead to my "creative" trip lever connection shown below. Even still, the flush action is smooth, and the tank ball sits squarely after the tank drains; the ballcock closes the flush valve after the tank is full.
That said, I'm having a couple issues with the diverter valve: the first is that water is constantly flowing to the rim holes as the tank is refilling, even after the bowl itself is full. This causes a long (and expensive) tank refill time, as the now over-filled bowl is constantly emptying as well. I should note here that I know it's the rim, as before I turned it back on, I poured water through both the siphon (visible just below and behind the flush valve in the first picture, and at the back of the tank in the second picture), as well as where the diverter connects to the front side of the tank: the water came from the rim, confirming it's being fed from the diverter during the refill.
I've adjusted the screws as described below:
I did read that these two screws should be adjusted in tandem to solve my issue: if that's the case (pun completely intended), I haven't yet found the correct combination of screw positions to solve this first problem. Currently I have the yellow all the way open, and the red about halfway between open and closed.
The second problem I'm having is that at the end of the tank refill, as the brass arm and ballcock are slowly closing the flush valve, water pours from the underside of the top diverter "cap." The water runs down the backside of that casing and tube here:
I'm also under the impression that the diverter assembly operates under a vacuum. If that's true, I've broken that seal and introduced air into the system: I've removed the red screw completely, and looked inside the casing. I could be off base there though, and me having removed that screw had no negative effect.
Any suggestions as to how I get the bowl to stop being constantly fed water during the tank refill, and how to stop water from gushing out from under the top of the diverter? Thank you very much in advance, and I'm happy to provide more info, photos, or videos upon request!

I've adjusted the screws as described below:
- as best as I can tell, the yellow screw slows the overall flow to the diverter: when all the way open (counter-clockwise), water moves quickly to the diverter. When all the way closed (clockwise), water still goes to the diverter, though much more slowly.
- the red screw, when closed completely, cuts off all water to the diverter: neither the tank nor the bowl are being fed. When open completely, water flows quickly to both the tank and bowl.
