I wouldn’t yank the welch plug just yet. Those motors don’t "lean sneeze" like the bigger motors. I would check the inside of the carburetor bowl and make sure debris hasn’t plugged up anything in the bottom. When these motors sit, the sediments will sit along with the old gas. I would see about getting a plastice float if possible, if you end up having to rebuild the carburetor. I’ve rarely ever had to rebuild any of those carburetors, but they can get plugged up in the bottom end, occasionally, when gas dries up and shellacs down there.
As far as the cam follower goes, that model didn’t have the roller at all. There was just a straight rod coming off the carburetor and it rides on the cam on the mag plate. Over time, a divot will wear into that cam and it will need replacement. The rollers were added in 1956. 1954-55 Johnson 5.5 was the only models without the rollers.
