What determines the bowl level in a toilet? Not the tank but the bowl. I replaced my old fill valve and flapper with one of the "Korky" fill valves and now the bowl has about half the amount of water as the old valve.
I called the factory and they told me that is was controlled by the toilet design. If true why did it change with new fill valve and water level in the tank is exactly the same.

Three things:
1- The time the flapper stays open during the flush.
2- The volume of water trapped between the flapper and bowl following the flapper close and the time at which the vacuum is broken in the internal trap.
3- Flow rate and duration of the bowl-fill line running from the cock to the overflow tube.
If the flush cycle time is relatively close, I'd say the issue you're having is reduced volume being delivered through the bowl-fill line.

I think you hit a couple of ideas. Yes I did put a new flapper in also and it does seem that it closes much earlier than the original.
Also the flow to the bowl fill tube does seem less than the original valve.
I did find out that if I hold the handle down keeping the flapper open longer that it does return to approximately the original bowl level.
I guess maybe I should use the simple flush for #1 and the hold down for #2

You might want to check the bulb on the bottom of the flapper. Some of them are made with a water saver design that doesn't allow the flapper to float when you push down on the handle. Also if the chain is adjusted to long it won't pull the flapper up high enough to float when you release the handle. Easy to check, pull the lid, push down on the handle and release, the flapper should stay up until the tank is nearly empty.
