My thoughts, too. If it has been sitting for a long period of time, then a blockage can enter the filter and strange things have been known to happen with filters. Change both the fluid and filter, since it will need to be done anyway and see what happens!

Talked with Vince O tonight, he said the relief valve is stuck. I'll attempt to pull it out tomorrow and try his recommendation. All the roll pins are in good shape and the fluid looks clean as a whistle. With some luck it will be a relatively easy fix.

Jack that rearend up and make sure that it is very stable if you run it and try to unstick that valve!!! I had a stuck valve once on a 129 and I had it jacked up, but not as stable as I should have. When it released, it took off on me and ran into my garage--right over everything and only stopped when the snow blower on my 149 held it back. I should have been safer in my work and got very lucky--just trying to keep you from repeating my stupid mistake!

I hate to say it, but I believe had I been there when that happened I would have been rolling on the floor laughing. I will take a page from your book and make sure its up on stands before I give it the gas.
