I am referring to in the figure is on the top right side. Holding down
the flush lever does not really help. All the water is emptying from
the tank OK. The problem is there is not a lot of water in the bowl
initially to get the flush process going.
When the bowl has a lot of water, it flushes fine.

So you are saying the amount of water in the bowl between the flushs
varies? Most designs have a plastic or metal tube that feeds a small amount
of water into the bowl by way of the overflow pipe as the tank fills. This
is how the bowl is refilled. If this is not done, then the bowl will often
not be refilled to it's design depth.
