In this video, I remove and clean the carburetor on my 2010 Champion 2000W generator. After not being used much for 3-4 years the carb jets were gummed up leading to hard to start and poor running condition. It would surge a lot and only run with the choke wide open. A little TLC got it back in good running shape again.
I found that the fuel farm in Auburn Washington offers Regular w/o Ethanol pump gas, and has become my go to for all my small gas engines.
Even though I have become pretty good at rebuilding (or at least cleaning clogged jets), just get rid of the root cause.
I use it all the time, and have not had any carb issues.
You have a lot of patience. If I'd have had to r & r the carb again after discovering the jet problem I'd probably just walk away. Good work. I can't wait for your trip south.
