Blower help BM250 Belt issue!

I have an alignment issue with the 16 rib belt on a BM 250. The driven and tension line up perfect but the crank alignment is off .300. The pulley is too close to the block. Is there a spacer that small I am missing?
Any tech manuals would be helpful!
Lower pulley#891330
Thanks

Are you using the proper V-belt pulley? There should be a spacer behind the Drive pulley.
