The WMS layer capitalizes all key names, so you can change it to
"%START%" and it will work.

If you have need for "?start=" to work instead of ?START=, then you
would need MapServer to continue to be able to do that. If you don't
need that, or you can change other clients, then you could use a
Layer.WMS and change your mapfile.
