Woods port with case matching to transfers,20cc domes,28mm pwk's with 155 mains,48 pilots and needle in 3rd from top.It's the n8ba needle something like that.I run the lid with the last 2x3 inches cut out.White knuckle intakes with v-3 reeds.1500 feet above sea level.I'm running pump gas and the commpression is 175.I checked the compression at about 800 ft above sea.Which seems a little high for pump gas.I'm going to call the builder on that.
With all the problems I've been having I never changed the jetting.Ran like a top after the rings were broken in.
