Thanks all. Thought I replied last night but can't see it. Brother in law read manual and learned he had not purged (bled) it correctly so he did it again and she started right up. Father in law was trying to tell him what to do to no avail. Father in law not able, physically to do maintenance anymore. I'll pass all this along and store it for future reference as I may have to do it for him at some point.
Thanks for replies.
