I recently adjusted my vales .06/.08 and also rebuilt my carbs. They were done separate and driven in between. I'm now noticing a pinging sound coming from the carb barrel on cylinder 3. If I put my hand over the carb throat it makes the sound go away. It is doing this at idle of ~950. I will load a video of the sound. What do you all think?

Readjusted the idle bypass screws on all to 1/2 turn out. Cylinder 3 carb barrel still needed more turns to have both barrels in sync. Resynced left and right and readjusted mixture screws. Still no change with the sound. It also seems to be more prevelant when the motor is warmed up. Next need to do a compression check and a leak-down test.
