I bought this just a couple months ago, changed the power valve to a 9.5 tuned it to my motor and had a valve seat got bad, so im going to put in a 6.0 motor. This carb has less then 100 miles on it. Paid $420 plus tax and a couple power valves. Asking $350 plus shipping, still have the box and paperwork, located in marysville ca 95901
