I have a machine on which the Honda engine GX390 is mounted. I didn’t find more than the sticker for ideification. The same engine was mounted on a chipper, but we don’t have it anymore. As can be seen in the picture, there is probably a piece of the exhaust there missing? Or can the silencer be mounted differently? Or should that be so? The remains of a spring hung on the long rods from the carburetor to the lever. I found a spare parts catalogue in the net. But the carburetor and the rods with the springs are not included. Does any of you have a kpl spare parts list for the engine?
