That engine requires at least a 24:1 fuel/oil ratio to run and live. Don’t let anyone local tell you any different. They are very nice running engines, good idle and great power.
As has been mentioned….a pressure tank….is also required to run that engine in it’s present form. A fuel pump would have to be added to utilize a modern single line tank. That change would still requires the heavier fuel/oil mix.
You have a good find however, not may around that can be converted from a short to a long shaft that are complete with the kit to do that.
