Gasoline stabilizers are a farce as far as I'm concerned. Naptha, "white gasoline", should refill normal gasoline after draining and then running engine till it quits.
Adding **** to storage gasoline is insane as compared to draining and substituting pure fuel that cannot ever plug micro passages inside a carburetor. Think about this point.
Professional loggers laugh then shudder at the thought of using storage chemicals inside a five thousand dollar commercial chainsaw. It didn't take me long to switch from Mouse Milk to the real stuff for storage.
DRAIN then start the engine until it quits
Put in a half-pint
Start engine for a few seconds then stop.
