Thought I would convey response to fitting a Holley regulator and gauge as suggested.
The idle issues and stalling at low revs has been cured set at 3.5 psi.
The motor sounds great and cackles like a large Harley.
Last hill climb bettered PBT by 4 seconds with plenty left to go.
Thanks again all for your imput.

Fat Albert.
