But now I'm realizing it isn't providing much vacuum (MS says it's 4000 mtorr or more), and there is a ton of air exiting out the exhaust port even when left for 20 minutes. It does seem to be providing some vacuum, as it pulls in the sideplate some. But when I switched pumps on that MS, it immediately pumped down normally.
Obviously it is something I did wrong when rebuilding, but I'm wondering if anyone has any obvious ideas of what to check based on what I am describing. Would be much appreciated. Thanks.
