Thanks zoidberg444. I plan to order the Continental belt. I'm getting a little nervous about having the Dayco cranked up so tight.

I found this document but not really sure how I would measure it effectively. I'd likely go with the belt deflection at point B, but how to determine 22 lbs, I'm not sure.

EDIT: After looking at a hardware website, I may pick up a small spring scale with a hook. Canadian Tire has a 50 lb scale for a decent price. I could run a straight edge across the pulleys joining section B, pull down on the belt with 22 pounds and measure deflection.
