This Wilesco D101 (like most Wilesco's) has a slip eccentric and was mearly running backwards I suppose , I wasn't paying attention to that detail...lol (good catch) with a flip of the flywheel it can easily be made to change direction.
As Emily Litella would say, "Never mind..."
Re:Jensen #35 I believe I have a spare boiler for that particular engine , its yours for the taking if you want it. (Free)
I think the Model 35 (Why did I say "D35"?) project may have just moved up the list! (Look for a PM)
Thanks,
