Help! No Spark.

[seahorse1]

I have a 1968ish evinrude fisherman 6 horse. When I got the motor it had no spark to the lower cylinder. I pulled the flywheel and noticed the coil was cracked(Big Suprise). So I replaced the coil and no spark, changed the condenser and still no spark, points are both set a .020 and the wires look pretty good. Any Thoughts? Thanks, Jess

Set the points as follows. Have the flywheel key aligned with the fiber rubber portion of the ignition points. Adjust the gap so that a .020 gauge will pass thru but a .022 will not. Should there be any question of the points being dirty (touching the contact with your finger would cause them to be dirty), clean them with a small brush and acetone or lacquer thinner.

NOTE: Should the operating cam have a small portion on it with the word "SET" imprinted, align this portion with the fiber rubbing portion instead of the flywheel key.

I would suggest also that you replace the plug wires. They can deteriorate at the spot where they are clamped to the underside of the mag plate. And arc to the plate or the clamp and it's very difficult to see. Even though they look good otherwise. Good luck!
