I run a fleet department for a small town. We were having constant and ongoing issues with small engine equipment, a mix of brand new to very old stuff. About 5 years ago as a test I switched from buying regular gas with 10% alcohol to clear gas (no alcohol). I was not sure if it would help or not. Within a year more than half of the run ability issues stopped. I used to be constantly rebuilding carbs and other fuel related parts. Now I seldom do, and the equipment seems to start/run better too. I was not sold when I first did the test (I am very frugal and hate to waste money) but after dealing with it I am totally sold on no alcohol in small engines, especially older ones. If you can't but clear gas locally, go to an airport and buy airplane gas. The only issue with it is that it is highly leaded, don't put it it in a car with an cat converter.
