I only use SeaFoam on my Honda 2000 generator. I add an oz or so to a full tank the last tankful of the season or last use for a period of time. My Honda will start with just a couple or three pulls of the rope next time I use it. I first used it when it ran just terrible after storage and it cleaned up the system in just minutes and Honda ran perfect ever since.
