I'm going to look at a used 1990 Evinrude (100 hp). I want to see how it

it will start if I attach battery to solenoid and jump solenoid.

Wrong assumption. This is a battery ignition... you are thinking back
to the old magneto days... a connection to the ignition for power will
be necessary.

2 questions:

1 - how can I shut it down. Can I ground a pin on engine wiring plug? If so,
which pin?

See above. Disconnect to shut down.


2 - which pin on plug will apply choke, or is it a richener?

Red lever on enrichment solenoid.

Should I just
give it a shot of starting fluid instead?

Hard on 2-strokes... last resort only.
