I was told to take the external belt off, then take the inlet off. Once both are off, I am supposed to turn the impeller by hand (from the back) and see if I hear anything. I was told that if there's a metal grinding noise, it's the impeller rubbing. If it's the belt that's slipping, they have to fix it
which sucks! I'm going to take the new serp. belt I have on my 88 and switch it with the serp. belt on my 93, and see if I still smell a burning rubber smell. If that's the culprit, I'll be happy. If not, then I think I'm not going to have any other choice but to take the s/c off and bring it to Powerdyne to have them take a look at it. I'll definately keep you guys updated, later, Keith
