0437209 EVINRUDE CARBURETOR ASSY., 88/90 models

Start By:a. remove fuel filter base 1. Disconnect fuel lines (1) from the fuel injection pump. 2. Remove six screws, and remove throttle linkage cover plate (2). 3. Place an alignment mark on the throttle shaft and the throttle linkage. Slide the linkage off the shaft. Remove bolts (3). Remove turbocharger oil lines (4) bolt (5), fuel lines (6). Disconnect fuel supply line (7). 4. Remove fuel ratio control line (8). Remove heat shield (9). Label and remove fuel shutoff solenoid wires (10). 5. Remove cover (11) and cover (12). 6. Loosen bolt (13). Leave a gap of 3.2 mm (.125 in.) between the washer and the gear. 7. Use tool (A) to remove gear (14). 8. Fasten a strap and a hoist to the fuel injection pump housing and governor. Remove bolts (15), nuts (16), and remove the fuel injection pump housing and governor from the engine. The weight of the fuel injection pump housing and governor is approximately 26 Kg (58 lb.).Install Fuel Injection Pump Housing And Governor (Later)
1. Put O-ring seals (17) and (18) in position on the fuel injection pump housing and governor. Put clean oil on the O-ring seals. 2. Position the fuel injection pump housing and governor on the oil manifold and the timing gear plate. Fasten with bolts (15) and nuts (16). 3. Use the following procedure to put the No. 1 piston at top center on the compression stroke. No. 1 piston at top center (TC) on the compression stroke is the starting point for all timing procedures.a. Loosen hose clamps (19), bolt (20), and remove the breather from the valve cover. b. Remove the plug from the flywheel housing.c. Turn the crankshaft clockwise (as seen from the front of the engine) until a 3/8"-16 NC bolt (21) at least 2.5 in. long can be installed in the flywheel through the hole in the flywheel housing. Do not turn the crankshaft counterclockwise. The rocker arms for No. 1 piston can be seen through the breather hole in the valve cover.d. Check to see if both rocker arms for the No. 1 piston can be moved backward and forward by hand. The No. 1 piston is at top center on the compression stroke when bolt (21) can be put in the flywheel through the hole in the flywheel housing, and both rocker arms for the No. 1 piston can be moved backward and forward by hand.e. If both rocker arms can not be moved by hand, the No. 1 piston is not at top center on the compression stroke. Remove bolt (21) from the flywheel and turn the crankshaft clockwise one full turn (360°). Install the timing bolt in the flywheel again. Check to see if both rocker arms for the No. 1 piston can be moved backward and forward by hand. 12. Install the gear and bolt (13) on the fuel injection pump camshaft without the washer. 13. Install tooling (A) in the fuel injection pump housing. Push on tool (A) and turn the fuel injection pump camshaft. When tooling (A) slides down
