I bought our grandson a 2019 tao Rock 110 that has the lever shifter by your left foot for D, N, R. I have been looking for a replacement carburetor. All the ones I seen came with the breather but the breather that comes with them doesn't have the spot to hook up the hose from the crank case. Why is that? Also I can't find one that looks like his anywhere. That is the year an model on the front of the frame.
