49cc 4 stroke Huasheng 142 bicycle motor retail

Product Name: 49cc 4 stroke Huasheng 142 bicycle motor retail
This is a very lightly used Huasheng 4 stroke motor for converting a bicycle to a motorized bike, but it can also be adapted to many other projects. Sold as is: It runs great when cold but I could not get it to idle or run well when warm, I spent several hours trying to tune it and it just wouldn't run good warm. I took the carb apart and cleaned everything throughly and it seemed to work better but only for a short while. Might need a new carburetor, but it is practically brand new so I'm not sure. Gas tank has a couple small dents. Came that way :( The last picture is retail it mounted on my bike for reference, bicycle is not included. Note I trimmed the plastic edge of the air box to get it to fit on my bike. I bought this months ago so unfortunately I can't return it. Just trying to recover some of what I spent ($200). Hopefully a mechanic better than I can put it to use. I will ship it with the oil drained, carefully packaged in a double walled box.
