What can you tell me about this spark plug?
Hey guys here to pick your brains a little, I installed a new Holley 2bbl 500 cfm carb,and it runs fine according to me,but the tail pipe of my exhaust have turned black inside,like if a rick condition exist, but my plugs read lean, plus I get this gas smell wen the truck is at idle,what do you guys read wen you look at this plugs?Here are some pictures. Thanks in advance for your input.
