I have a four winds with an onan 4 K gen. that I use maybe once a year. It is always a pain trying to un-gum it when I need to use it because the gas goes bad in-between uses. Should I drain the float...
I have found that a can or 2 of Seafoam with each fillup will keep everything running well.
I also try to run the Onan 4K monthly under load but it has set at times for longer than that and have never had any problems with mine in 10 years with more than 950 hours on it.
