engler injectors set at .002. Tim told me to set the barrel valve between 18-20%. I'm at 18%. Waterman ultra light pump that is fresh from rebuild by Waterman. Feed line goes to shut off valve then on to top side of barrel valve. Secondary, main and high speed all feed into 3 into 1 block with 1 #8 line going into tank. I'll do a leak down on the motor this week, it only had 12 shows on it since new when I got it.
