take a quick look around and you'll find the answer..
it's recommended to use 50:1 because lots of engine jammed up with 1:100.

It wasn't as much as the jamming up was the concern. It would be fine running at WOT but when you came to an idle it wouldn't save enough oil to keep the bearings and moving parts lubricated.
The biggest problem arose when you shut it down and it sat for a while and restarted the oil on the moving parts had drained off and you were starting a dry engine. That is where most of the failures came into play.

"Hi, new to the forum. My neighbor has a 75hp Johnson, pre 1970. We are trying to find out the fuel mix needed for that motor. I can get the model number if needed.
Thanks,John Sutton"
