Me again, topic of the Bolens cutter deck\belt. 30048s deck, i ordered the correct belt from Outdoor King, fitted it, when i tensioned it up the tensioner ran out of thread. i have had 2 other belts of different part numbers on the deck and they were even worse, i had to put a big spacer between the tension nut (that you screw up to tension the belt with) and the stopper to get more thread to use. that worked, but, getting the new RIGHT belt i thought i would be done with that spacer. No, not the case, it is tensioned right but i'm out of thread, pulleys were changed but they are the same sizes. there is nothing else that can change the "length" of the belt. Any ideas? i can post photos if need be.
