Carbon Buildup on intake valve

When I removed my carb I notice that the left intake valve had some carbon buildup on it but the right valve look new. Could this be a sign that the left valve is leaking combustion gas back thru it?

Have u adjusted your valves and maybe the valve seat surface isn't good so it leaks

Yeah, I will check the valve clearance.
