Awsome info! Thank you for taking the time to type all that out and do the conversions for me. It does have a site glass and I let it continue charging for a minute or two after it went totally clear so I guess I charged it ok. Unfortunately that was a couple of weeks ago and it now foams up when it cycles so I guess I still have a small leak some where. Oh well. I'll see how long the charge lasts and decide then if its worth replacing more parts or not. Thanks again for the info.
