Winterization - Draining Carbs

Post by jsthomps »



Do you really have to drain the carbs if you have fresh gas with Marine Sta-Bil fuel stabilizer and Seafoam added. I thought the whole purpose of using these additives was to keep the gas stabilized over the winter so who cares if there is clean stable gas in the float bowls.

Stabilizer will keep the gas from separating in the tank - but the carburetor float bowl is vented. If you let it sit for weeks, the gas inside the carburetor will evaporate, leaving behind whatever nonvolatile content is in the fuel: sludge, lacquer, etc. So better to run the bike with the fuel off until the carb float bowl is emptied.
