The only problem I’ve ever had is bad gas…..today’s crap gas with ethanol goes bad way too quick. Get in the habit of running your gen every few weeks, and use Sta-bil. If storage is necessary, run the thing outta gas & squirt a little oil in the cylinder. Ethanol is for drinkin!
Simple solution for any gas powered equipment that sits for long periods between uses is to use Marine gas or buy ethanol free gas… cost a little more but you will not have carb issues ,
So if you have Marina that sells gas to boats or a ethanol free gas station get a few gallon and use that.
