Push or pull it to bump start it if its a manual. Worked for me after my build.

Ah.
Not the side seals?
Did you check the housings for flaking or chatter marks?

Sorry man. I think you'll need to rebuild it again, properly. Do it right or do it twice.

Its not uncommon for the compression to be low following a rebuild. I would recharge your battery and keep trying to start it. Good chance you'll pick up some compression during the first 5-10 minutes of run time. I would at least try that before tearing it back apart.
