Reply To: A question about point gap and timing mark

[Dale]

I am coming late to the party here but here I go.  I learned a long time ago to use a continuity light and a dial indicator to set timing.  Two cylinder engine set one set of points at spec setting.  Hook up continuity light to points wire on that cylinder, ignition switch on, dial indicator in spark plug hole turn motor to top dead center, zero dial.  Slowly turn motor opposite of it’s normal rotation  watch light.  When points close the light will brighten up.  Read  and note the dial when the light brightens.   Move dial indicator to the other cylinder, set TDC on that side move continuity light to the other point wire.  Set the points on second cylinder to match the first.  Remember  “wider points make more advance, narrow points to retard timing”.  I taught three snowmobile shops how to set timing many moons ago.  I learned at our distributor maintenance seminar.  I made my own  continuity light out of a big flashlight and I still have it.  I check outboards with this arrangement.  Gotta make sure advance stays in the same spot for both cylinders.
