With the flywheel at the middle of the 3 |||, one cam mark should be straight up, the other straight down.
Just a note, to take better care of batteries - if you crank on one a lot, get it on a charger as soon as practical after. LA batteries do not like sitting discharged, the longer the worse.
Give it a 1-2 second shot of carb cleaner, and hold the pedal a little open, see if it fires. If it does, you have spark at the right time.
