timing

[rik1234]

hi just purchased a evinrude 4hp and the points have been fiddled with i know how to set the timing but i dont have a manual and dont know the space i need to use with the fila gage ive been told that its 025 but set the time for that and its still slightly out. just wondered if that is right cos if it is that means that its my error and i will try again.

Re: timing

The setting is 0.020". If the points are new, set at 0.022" to allow for seating of the breaker block.

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.
