Hey guys wondering if y'all ran into this before, I have a ? Year Hustler with a 16hp Kohler, the belt I'm using is a dayco max 1078. It works ok but is a little loose for my liking. Tranny pulley is 9" the engine shaft pulley is 1 3/8", center to center is 13 3/8", supposed to be 1 3/16" wide but I think 1 1/4"could work ,any math genius's out there to tell me what belt length I should using? I've read 1" play is what you want? Been lurking for years y'all are a wealth of information
