Float valve filter is clean
Float level looked good
Adjusted mixture screw in and out (set @ 2-1/2 turns out now)
Main washer sitting next to float valve in pix, and installed
Jets: dunno know, didn't look, assume stock
Aux tank is vented; is designed for bike work
Air filter stock and clean
Muffler stock (as far as I know)
Idle is fine. Raising/lowering had no effect
Chesterfield, VA, ~236' ASL
I did not dis-assemble the main jet needle, so don't know anything about a white plastic washer/spacer.
