Despite the instructions that the pulley be a certain distance from the front I've never paid much attention to that on my 108. It's been cutting grass for 35 years. As long as neither pulley hits anything else and the belt is tensioned, it seems like it should work OK. Of course, the correct belt helps, and maybe that's why I've never really paid attention to this-I don't think I've ever had to adjust the tension on these pulleys. I just warp on a new belt when the old one breaks every 3 or 4 years.
