Ok maybe I'm just not that good at searching but it seems like I've never found a real good detailed breakdown of how to install new points and properly set the gap. I've checked the service manuals and few threads on said operation but they don't seem to make it as clear and simple as it should be. For the record i'm no master mechanic. But, i do understand the theory and have swaped a point set between a working n non working kohler with success. Not sure its timed right though.

So what I'm hoping is that a few of you can breakdown and simplify the process on this thread? Pictures would be great but a movie breakdown would be awesome.

figued I'd attach this pic in the spirit of the topic-though it probably showcases the need the properly mangae the fuel system in a Kohler.

How to set the points on a Kohler engine -

Adjust the points by first positioning the piston at TDC on the compression stroke. Then slightly loosen the set screw on the points and place the flat screwdriver in the slot on the upper part of the points bracket to widen and narrow the point gap. Then use a .020" feeler gauge to set the gap.

For a more accurate setting of the ignition timing, use an automotive inductive strobe timing light with the
engine running at an idle. This cannot be done with an aftermarket steel flywheel having no timing marks.
On a Kohler engine, if the screw that fastens the points to the bracket is hard to get at with a screwdriver on the
equipment, then install an Allen head screw and use an angled Allen wrench to adjust the points.

NOTE: If the ignition timing is set right and the engine kicks back when trying to start, sometimes, but not always, the compression release isn't releasing enough compression from the combustion chamber. Try setting the valve clearances to specs and see if that makes a difference. If the timing is retarded to reduce the possibility of kickback, then the engine will run sluggish and not produce enough power.

Also talks about point savers further down the page.

I found it to be a "time by ear" fine tune once you sneak up and get close with all the above.

The SP mark on the flywheel shows in the shroud inspection hole when timed properly but there is room for excessive spark tolerance several degrees either way depending on how and what angle of eyesight you view the mark.

The points adjustment is crude for the amount of adjustment you seek in fine increments of degrees.

Excess advance is not good for the Kohler, IMHO..
