I had a 3 hp Briggs and Scrapem engine given to me with 30 year old gas in it and the tank and carb was a mess. The old gas poured out like a syrup. I shook the tank with rocks in it to first get rid of the course stuff. Then i used E-85 and soaked it and shook it around every day. I drained it and put in new E-85 and repeated the shaking every so often. The crap that came out was a lot. It cleaned it almost to metal. Then rinsed with Dawn dish soap and water and let it dry. The carb wasnt as bad as the tank but still pluged up solid. I got that clean as well and new fuel pump diaphram. Even the long tubes that reach down into the tank were plugged solid. But e-85 works wonders if you give it time. Thought this might help you tractor guys.
