Thanks guys. I was hoping a 16x12 or 14 would be ok?? Even a 15x14??

As for the manual I have still not had any luck searching the web. I will try just engines.

This back starting techneque, I read you should spin the spinner and not prop??? does it matter?

Is it a question of feeling the compression and then spin it clockwise so it bounces against the opposite compression and then it starts???
