I see no one has found a smooth pulley for your set up tighed1...so I am ordering the ribbed one and doing this mod this week before returning to US 41....no rain this time, I hope...unless there is something I missed thru all this read...32krazy, this worked for your C3 set up, right???? Cause that is all I am running....may go ahead and put my new belt on while I am at it...
