So my Mother's 3 or 4 yr old Briggs 3.5 on her mower was running rough lately (surging)...so I took the carb apart to clean and replace the gasket/ diaphragm (per Donyboy73's excellent video)...i noticed there was a lot of dirt and junk in the carb as well as in the gas tank..
I mentioned this to my Mom and she said "oh, maybe I shouldn't be checking the fuel level by sticking my (dirty, gardening gloved) finger in the tank?"..... Uh, yeah...no more sticking a mud covered, gloved finger in the tank!
