Its not a quad but its a 97 XR400 I just found this dent and I dont know if its bad or how long its been there no oil is leaking out and it shifts just fine. Should I replace it?

The carburetor doesnt want to function at full throttle almost like its inverted and no throttle is full after a valve adjust it idles properly now however it still doesnt like to go past 50% any ideas?
