I don't use fuel stabilizers, I never have gasoline last very long around here. I also try to run all my 2 cycle equipment dry for storage, meaning empty the fuel tank, start the item and use the choke to run it dry, then you avoid varnish and gumming up from sitting. I use all my old pre-mix gasoline in my Allis Chalmers CA to mow grass after the wood is cut too. I'd take a good Allis Chalmers over a Kubota any day too...heh heh.
