Assembly and testing of a super cheap 4T kart. Update 2021: at the end of the fourth outing problems were found with the "Stage" engine. We therefore made a dedicated video for reliable engine tuning, revised and corrected: https://youtu.be/jq1hPEqzkB0 The reliability problem should be solved by the valve kit. The engine is now no longer the 210 cc but the 200 cc which should also guarantee greater material compatibility at the cost of a slight drop in power.

Carburetor: you can leave the original one or fit a 26mm Mikuni Clone type, which is easy to find on ebay. You do however need to adapt the carburetion, only for users who are at least a bit experienced.
