I'm new to the blower world and in the final stretch of getting mine ready to run. I will be asking some questions here to try to prepare myself for the launch. Blower is 6-71 on a smallblock.

The first question has to do with the idler pulley. Most pictures I see of setups has the idler pulley running on the teeth side of the blower belt. Is this necessary? It would appear to do just as good a job running on the smooth side of the belt. In fact I need mine to run there to obtain needed clearance. Is there any problem with this configuration?

Thanks, Max
