This was my back up/emergency generator and is several years old, but with only about 5 hours run time.  Always stored inside with fuel preservative.  This gen-set runs great and I am only getting rid of it because it is not big enough to run the AC on my recently acquired camper.  So, I had to up-grade to a larger one.  Has one slightly bent axle (it shipped to me that way) but is no big deal because this is a light unit and carries just as easy as it pulls..
