Hello everyone. Had a project this weekend with a very typical small engine issue and thought this might be a good time to go through the general troubleshooting process for root causing lean surge. This example was a GX240 with Keihin carb but hopefully some of this discussion helps describe how you'd go about similar issues on other carbs as well as typical tools required. Sorry about the video turning 90 deg halfway though, I had a little helper film this part so I could use my hands.
