Default Compression test

Finally got to do a compression test on 2 of the spark plugs port before the tester failed. Anyway here is what I got:
Front rotor top plug: 95PSI max and drops to 0
Rear rotor top plug: 90PSI max holds steady
I will get a new tester and test the bottom 2 plugs tomorrow.

Also does a 12A have an electric pump, if so I know it is hard wired into my headlight switch. and my carb fills with gas as it doesn't shut off so I get to play find WTF the previous owners did.
