Hi. I just recently got a ‘59 MS50. I got it running after sitting for decades.
The cap says to put 5 “cups” of oil in per gallon of gas. It measured out to like 6 or 7 ounces! That’s thick!
It ran like garbage on that mix, so I cut it down to probably 35:1 or so.
It runs much better. Will that be safe to run in this old lady? What are others running?
