Having problems with my vacuum PTO. It doesn't work all the time.
Tracing vaccum lines. One comes from under then engine. I'd think most vaccum would be manifold vacuum, and come off around the base of the carb.
This one seems to come from directly under the fan assy. Something called an e-vac. What is the e-vac valve/connection????
I thought it would be manifold vacuum. When I put my finger over it, the engine ran a bit differently, and them cleared up when my finger was removed.
So---what is the 'e-vac' thing, and how does it work?
