2010 Kohler 752cc
Family: AKHXS.7252GC
Model: CH740
Spec: CH740-3136
Serial: 4008606161

Last year it had all kinds of running and charging issues. I changed the stater, rectifier, battery, broken flywheel key, cleaned carb, and converted the coils to the older style off a parts engine I had sitting...
