Anyway.... you guys sure are getting "all excited" for my Iowa Spree.
Gee, sorry, I didn't think a little story and some info about Iowa Sprees was Hijacking your thread.
Somebody was trying to get some more top speed by removing the thrust washer and squeezing the pulley halves together, forcing the belt to ride higher.
I'm sorta guessing here, but I think that when they tightened the securing nut, it actually hit on the splines and when they ran it, the whole thing was loose and the inner sheave wobbled into the case.
Then they added the washers so the nut would actually tighten.
Have you checked for any play on the crank bearings? Any felt movement is too much.
You really should think about replacing the bearings and seal at this point anyhow, especially since you are almost there.
It's common knowledge among tuners and engine builders that when a 2-stroke engine sits with the spark plug out, the bearings are at risk. What happens is, as likely as not, the piston stopped at BTDC and the transfer ports are uncovered. That leaves a direct open path to the crankcase where condensation occures. Seen it over and over during the 40 plus years I worked as a mechanic.
But it's your call.
