HELP! Crank shaft end play

[walcen]

Hello folks.
Need specs on Poulan 3700 crank shaft end play(float), I have around 20 thou, may be a little excessive. I can machine up some new spacer from copper round stock if need be. Any help would be greatly appreciated, Thanks.

I’d not use copper, too soft.[emoji848]

I did use the shims for the old Delco Remy points style distributor on a little red Homelite that had excessive play.

Or just seat the McGill drawn cup needle bearing a tad deeper.

Thank you so much for your reply.
Hmm!! Tap the bearings deeper, I didn't even consider that, Not sure if that'll work. The thrust washers that are on it appear to be copper however they may be bronze, I also have brass stock that I could use.
