Decarb, take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas(fuel to oil ratio is 50:1). Put the rest in a spray bottle. start the engine, and let it come up to temperature. Then remove plugs, and them some real good shot of seafoam into the cylinders, replace plugs, let sit 15 minutes. restart, and spray the rest of the seafoam into the carbs, so the the motor almost stalls, wait and repeat until the seafoam is gone. Then take for a wide open spin. Then put in new plugs, ad premixed gas to the tank, and take it for a wide open throttle spin. it is going to smoke like a house on fire, during this process.
Take it out for the wide open spin while using the one gallon with sea foam?" yes, burn the fuel use the rest in the tank, then fresh fuel/oil/ and new seafoam mixed according to maintainance schedule on the can. it will keep a clean engine clean. Also change the spark plugs, the decarb will ruin the old plugs.
The author is speaking of doing this at the lake, pond, bayou, or where ever so you can effectively run the motor. Seafoam does a great job of decarbing.
