just bought this motor; previous owner of course did not have the manual. I need to determine the spark plug gap and fuel/oil ratio. does anyone here know this or know where I can find this info online? I'm surprised to learn that I might need to purchase a service manual just to get these basic specs.

pretty sure the ratio would be 50:1, but I would like to know what others think

Thanks
