Ross, Check the orfice behind the plug next to rate of lower screw. Not behind the plug where the light spring and check valve is. The orfice can be removed with a allen wrench. Depending on the year of machine there could be a second orfice that is straight down from the needle and seat that is under the lower solinoid. You would reach down with allen wrench with needle and seat removed to get at the posible second orfice. Good luck. Dan
