I am using 1/4" ram. I think that I am also loosing too much suction and force thru the packing nut. I am now experimenting with using an o-ring on the ram and/or for packing. Hand tested it and it seems to work better. I will install back on the engine next week and report back. My boiler is a...

PM sent.

PM Research does not have any to sell or copy. If anyone has a copy that they could reproduce for me I will pay for copying and postag...

Wasn't this engine a build series in Live Steam during the late 1980's?
