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...

Muffler is not plugged because I can feel my hand being sucked in at the tail pipe instead of air coming out. It is like the engine is turning over backwards. I have heard of small engines doing this like in a lawn mower when it stops suddenly like when it hits something. Does anyone know which way the fly wheel should turn?
