I'm finally finding a little time to tinker with my E16--and again the disclaimer: it's all new to me, and I'm not mechanically inclined. The Service Manual/Owners manuals seem to suggest that there should be 2 belts, and in fact, I can see pulleys for 2 belts, but there is only 1 belt there now...which is perhaps part of the problem? Any belt tightening/replacing tips/tricks? Thanks, -- Arnie Sabatelli
