Small bubbles at spark plug thread
Hey guys I just replaced my spark plug with the NKG one and noticed after I had gapped and placed it and was running the motor a very small bubble was eminating from where you screw the plug into the head ,I've tightened the plug as much as I can without stripping the thread , is this common or is it an issue I should address and if so how ,with a bit of thread tape ?????
Cheers guys Henshooter
