Kohler 5CKM21 no compression in both cylinders

Finally got to go camping last week, started the genset to heat lunch, it started right up, ran for no more than 10 mins then died. Would not start again. Checked fuel pump plenty of fuel squirted out...

If it has compression release like on Briggs, you have to turn back the crank a little to get valves to close. When engine RPM is high enough the compression release disengages.
