Mike. Thank you for your offer. I have talked extensively with Cliff on this one and as you said he was very helpful, but having just moved to a new building and his new workshop not yet as he would like it he was not able to confirm that this is a common problem. I suspect that some people may have the problem crop up and not be aware of it. The engine still runs on one burner, but not with the gauge showing 75 psi! I have been passed a couple of test reports where the problem was mentioned.
Thanks again Bert. ------------------------- Bert & Edmunda [EMAIL PROTECTED]
