I'm converting a 1972 evin

I'm converting a 1972 evinrude 100hp from a
cdi system to a breaker point style with an
ignition coil. What should the gap be set to ?
Also at what speed should this engine idle at ?
 
"ON a flushette, idle at 1000r

"ON a flushette, idle at 1000rpm. The idle will drop to normal when in the water.

I don't know if the point setting will change, being converted to automotive ignition, BUT here something for your reference.
(Point Setting Of Battery Capacitance Discharge)
( Ignition Models - 1968 thru 1972)
(Some have points - Some do not)
(Joe Reeves)

The points must be set to .010 but no wider than .010..... BUT in some instances due to a possible slight inaccurately machined crankshaft lobe or a slight offset of one set of points, a setting slightly less than .010 would be required as follows.

Whether the crankshaft has two or three lobes, when setting the points, check the setting of the points on each individual lobe by rotating the crankshaft by hand.

You may find that setting one set of points to .010 on one lobe, then turning the crankshaft to the next lobe, the gap measures .011 or .012 (too wide). This is where you would need to close that gap down to the required .010. A gap too wide can result in a ignition miss when throttle is applied.

Bottom line, pertaining to the point setting at the various lobe locations____ .010, .010, .009, is okay____ .010, .010, .011 is not!
