After watching your YouTube video on "How to Clean a Two-Cycle/Two-Stroke Engine Carburetor". I was able to repair my carburetor with no problems. Then I just removed the return grommet and installed the return tube into it, then put some oil on the grommet and inserted it in the fuel tank, then attached it to the carburetor. Here is the copy of the video. https://www.youtube.com/watch?v=Z18WwhxEtxI
