I guess I'm not that lucky, I have had problems with carbs on small motors in the past, If I don't run or drain the carb bowls sooner or later I will have to take them apart and pour the snot out and clean the jets with spray. I have used Sta-Bil in mowers and snow blowers seems to work, but I drain the carb-bowl in the generator,and also run it when ever I get a chance. I have two 1500 watt heaters I use for a load.
It seems the more I run that little screamer the better it runs. And
I have priced a onan microquiet 4000 carburetor.
