Fuel inlet nipple A. 28 kPa (4 PSI) 3, Diaphragm XP Model Only CARBURETOR REMOVAL Inspect parts for corrosion dammage (shaft, butterfly, spring screw, check valve housing, etc.). PUMP DIAPHRAGM LEAK TEST TYPICAL To remove carburetors from engine, proceed as follows: Remove air vent tube support. Unlock retaining slides holding air intake silencer base. Remove air intake silencer base from watercraft. Remove screws holding flame arrester base support to cylinder head cover. Unscrew base retaining screws then remove base from carburetors and move to front of watercraft. Turn the valve to OFF position. NOTE: For fuel line removal, use pliers (P/N 295 000 054). Disconnect pulse line from fuel pump. Disconnect fuel fuel supply line from fuel pump. Disconnect fuel return line. Disconnect oil injection pump cable, throttle cable and choke cable. Remove screws no. 6 and lock washers no. 7 retaining carburetors. All Others Models Remove 4 bolts no. 8 and lock washers no. 12 from rotary valve cover then move carburetors and rotary valve cover on top of engine. NOTE: When removing rotary valve cover , pay attention that the rotary valve stay in place, other-wise it must be timed. Remove carburetors from intake manifold. Disconnect fuel bypass line between carburetors (twin carburetors). Remove carburetor(s) from rotary valve cover. DISASSEMBLY AND INSPECTION Using a suitable pump gauge tester, perform the fol- lowing test proceeding as follows: - Install pump gauge tester (P/N 295 000 083) on pulse nipple. - Pump tester until it reaches 28 kPa (4 PSI). Diaphragm must stand pressure for 10 seconds. If pressure drops, replace diaphragm. TYPICAL PAGE Sub-title with part number(s) from exploded view followed by part name(s).
