The wire going under the flywheel is the ignition kill switch. There will
be no spark if this is connected to ground. If it is not connected to
ground and there is no spark , then it's time to check the ignition points,
coil and condenser.

Just acqired a 1954 Evinrude 25hp outboard with no spark at the plugs.
The wiring harness hanging from the engine has 4 wires. 1) Positive
starter lead, 2) ground lead, 3) wire conecting to the choke solenoid,
4) wire connecting to a gear that has a cable attached to it that goes
up under the flywheel (either timing adjustment or linkage to the
carb).
My question is ... Do either wires 3 or 4 needs to be connected to
something to complete the circuit for the points to send current to
the plugs?
I attached starter lead to positive and ground lead to negative and
starter spins right away, but no spark.
Thanks for the help.
