Hey David, Just started working on my peds to get them ready for the spring, Ha! None wanted to start so I drained the gas (stored full) and blowed out the carbs, went and bought some racing gas 110 octane leaded, mixed with my synthetic oil, and they run and idle better than ever, i also use a little Sea Foam carb cleaner in each tank. Should give it a try....racing gas is about $2.60 a gallon and wont damage the motor, they sell it a lot of places here in VA. Keep on Pedden---Doug D
