Mine squeaks when cold, and its tracking perfectly. I put it in the same catagory as backfiring,.......if it ever quits, I'll fix it !
In reality, if its not tracking on center, its time to fix it,....quick fix or not.
I would loosen the axle (but not too loose) and tighten the adjuster bolt
on the side it is rubbing on. But tighten only 1 flat (1/5 revolution) at a time. Just tightening the axle nut can change the tracking.
Or if belt tension is already quite tight, you would have to loosen the opposite side. But then you knew that.
