What I did was crank it...let it run 10 -15 mins. and when I turned it off I watched the fly wheel.
Too much vibration as flywheel settled down, so I cranked it again and turned off the fuel and watched it, still hard to tell so turned it back off and had a late brain storm....
Just pull the rope cord and see which way the FW turns...it rotated downward as I faced the FW.
So that's how I determined the starter had to rotate it CCW to crank it.
Wait, hold everything...I just grabbed the starter and there is resistance when I rotate the gear CW and no resistance when I rotate it CCW.
But if it's like a car starter the bendix engages the starter motor gear into the FW to crank and then disengages when the car is running.
Heck, now I'm confused.
I just looked up the manual on that engine and it says clockwise, or perhaps I am confused.
