I recently bought a used TaoTao ATA110-B. When I was digging the mud nest, left by some wasp, out of the valve (on the emission tube connected to the exhaust) I think I pushed too far in and damaged the valve. It has an arrow on it, which seems to indicate a check-valve. But after starting the engine, the exhaust is coming out of the plastic valve. I didn't run it before cleaning everything, but I can't imagine that is normal.
Does anyone know where I can purchase a replacement (generic or equivelant)? I can't seem to find one on-line anywhere.

Help is appreciated.

 

I dont know where to buy one, I didnt see it on my normal parts site, but you could just make a block off plate.. I don't think it does anything.. at least on mine the tube just goes up under the front fender and has a filter on the end.
