spent the evening putting in the bottom bracket, crank arms, pedals and
put the rear wheel on... but the chainline looks pretty off to me. the
chainring seems kind of far out, and the cog seems more towards the
middle. i know i can't adjust the spacing on the hub otherwise i won't
be able to use the flip flop... and there is a washer/spacer in the
drive side of the bottom bracket i can take out, but i'm not confident
it will be enough to make the chainline perfect. is there anything else
i can do? i think i can get it close enough to be safe, but i'd like to
get it as best i can.thanks,

what hub, bb, crank, and bb width? is using a shorter spindle a
possibility? if it's not a single-ring crank, do you have the ring
mounted on the inner side? have you measured the chainline (doing this
confidently can be clumsy at first, but it's pretty easy). have you
checked frame alignment to see whether it's a contributing factor?
by saying there's a "washer/spacer" on the bb you could take out, do
you mean like a freewheel spacer that's spacing out your cup or
cartridge? if so, that should go.
