FUEL PUMP
FUEL PUMP TEST
To determine if the fuel pump is operating proper-
ly, make the following tests:
1. Be sure fuel lines are not blocked, leaking or
have a stricture that would retard the flow of fuel
to the pump. The flexible hose should be carefully
checked for deterioration or cracks.
2. Remove and clean sediment screen.
NOTE: If the combination fuel and vacuum
pump is used, in addition, remove and clean
the air filter screen located under the cover at
the top of the pump.
3. Make sure all connections are tight after re-
placement.
4. Disconnect the fuel line at the carburetor and
connect the fuel pump gauge, Figure 16.
5. Start engine and run at 1800 R.P.M. normal
pressure should be 4 lbs. minimum to 5 lb s .
maximum. Stop engine and watch pressure
gauge. Pressure should not fall perceptible after
engine is stopped.
FIGURE 16
6. If pressure falls; leaking pump valves are indi-
cated.
7. If pressure is below specifications, attach the
vacuum gauge to the inlet port of the pump and
operate the engine. Gauge should show a mini-
mum of 6 inches of mercury for satisfactory
operation.
VACUUM BOOSTER CHECK
To check the action of the vacuum portion of the
combination fuel and vacuum pump, connect a
vacuum gauge to the inlet port and disconnect
outlet. Gauge should show 8-1/2" of mercury at
120 R.P.M. and 12" at 1800 R.P.M.
MANIFOLD HEAT CONTROL
Check the manifold heat control valve to see
that spring is in good condition and valve is free.
If damper shaft is stuck, remove the thermostat and
spring, apply penetrating oil or kerosene and tap
shaft for end play to break carbon or corrosion.
The shaft should not be oiled. When properly
freed, check springs and thermostat before install-
ing and replace them if weak.
CARBURETOR
CLIMATIC CONTROL
1. Remove t he carburetor Climatic Control Cover.
Check the heat control tube for leaks or obstruc-
tion and the choke valve and piston for free
movement. Choke valve should open of its own
weight when cover is removed.
2. Reinstall the cover with graduations down and
rotate counter clockwise to one point lean of
center graduation.
CARBURETOR INLET STRAINER
1. Remove bowl cover strainer nut, gasket, and
strainer screen. Clean screen and replace if cor-
roded or damaged.
CARBURETOR FLOAT LEVEL
1. Remove air cleaner, carburetor dust cover and
screws attaching carburetor air horn.
2. Disconnect throttle connector r o d, bowl cover
and check float level with gauge J-818-1 Figure
17. Float level should be 1/2".
3. To adjust, make sure needle is seated, raise float
and press down on float lever lip with a screw
driver. Bend only a small amount at a time and
do not disturb the curvature of the lip.
