HELP!! Wont start fo break-in!

Don't get in a hurry. 12 volts out of the battery is not enough especially with a new motor which is tight. Charge the battery for at least a few hours. The voltage should be 13.5-14 when the battery is fully charged. Unless your charger is a big professional model, the boost setting is only around 50 amps. Not enough to do much good. Your assembly lube should be good for a few spins. Did you pre-lube it before starting?
