Kohler CH23 Low oil pressure on one head

Hello,
i have an old exmark mower with a Kohler CH23 2 cylinder V engine, i have determined that i have great oil pressure to one cylinder head and almost nothing to the other side. i have the valve cover off of the low pressure side and almost no oil in the rocker arm area. The good side has oil shooting all over the place so that cover is on. Any suggestions of where the oil flow could be obstructed would be great. thanks much.

thanks much.

There is no oil feed to the head.
It gets there by splash.
You do not need much oil in the head.

Now what is your actual problem ?
