how do these work. i think i put too much load on the belt messing with the tensioner. swapped the belt on the 93 burb for the first time and have never messed with a serp. set up before. so instead of reading my manual (shhhaaa.....right) i tryed to loosen the bolt on the tensioner pully with just gave it more tension. /forums/images/graemlins/eek.gif so how do i back it off and how do i know how much to do so? /forums/images/graemlins/1zhelp.gif yes, this was a stupid dork move, let me have it. were's my dunce cap?
