I have the model 71 handle and purchased and installed the TFAA fba's and was wondering if its normal for them to buzz/vibrate or hum when gas or fuel is flowing through them. It happens on both the oxy and acet sides with and without the torch lit. I wont use the torch until I can find out if this is normal or not. Thanks
