What to do with a Cub you just brought home

First thing l would dbl check is the timing placement. Set the #1 cyl. to TDC as per the manual, then check that the rotor button is near the 1 o'clock position. I've had mine out of time by 180° and it would not fire. After that l would double check that my plug wires were in the right order at both ends.
Static timing should be good enough to at least get it to fire.
Also, did you install your battery as a positive ground? That could also be a problem.
After all that l would disconnect the on/off switch wire from the distributor to make sure the switch isn't causing it not to fire.
I try to work on the basics that don't cost a lot before "rebuilding" things that cost money.

Good luck

When you said it spins the engine really fast, that caught my attention. My 6 volt won’t spin mine really fast even fully charged. Could the valves be stuck and not allowing compression? Also stick a screwdriver or a tester in the ends of the plug wires to verify that you’re actually getting fire to the plugs.
