i have the same problem with my novi. i have had the blowere on and off the car a few times and one of the times everything lined up perfect... i took it off and put it back on and the pulleys were off by one or two ribs(i used a laser level to check it) but the belt dosent jump off or anything so im not that worried about it. try some shims and also the laser level really helps out a ton i would try that out
