[Diy_efi] small engine spark timing

[don.broadus at exeloncorp.com]

A retard on start up might be some help. The flathead design of the Kholer really wont respond
to advance like an overhead valve head would. I have a Bolens with a OHV 16 HP Kholer.  The Case Hydraulic drive really lends itself to steady RPM on the Pump. I thought most of the Big Tire 444's were Onan twin powered.

I'm now the proud owner of a 1987 Case/Ingersoll 444 garden tractor.
I'm giving it a much needed tuneup, which includes replacing the
condensor with a transistorized ignition module.  Well, that got me to
thinking about advance curves...  The points are driven by the camshaft
(single cylinder Kohler motor), and are kept to trigger the module.  The
module I'm buying won't have any advance but it wouldn't be that hard to
design one that did.  Can these little motors benefit from some kind of
advance?

thanks,
