In hindsight it seems to me it might have been automatically correcting itself and was kicking into counter clockwise rotation even though I tried so hard to make it run asz backwards. :stupid:
I might not have had the sence to know which way to push the prop while I was standing on my head and looking at it from reverse. But I sure did know before anything else, that in the limited 40" space I had in this tool shed, it was better to start the engine kneeling from behind it, so when it did start I could practically fall out of the tool shed doors and be the heck clear of that spinning 20" prop and all the accumulating exaust.
Thanks gentlemen for the helpfull input.
