Saab 96 - If the Engine Misfires; Reduced Engine Power

d. Check that the fuel line fittings at pump and carburetor are
tight.
e. If the engine has been cranked too long without starting, too
much fuel may have entered the cylinders and soaked the
spark plugs. Dry out the cylinders by removing the spark
plugs and cranking the engine with the starter. Insert dry
spark plugs.
f. Check that the cold start lever on the carburetor operates
correctly. Let the starter crank the engine while the accelera
tor is kept pressed down constantly 5—10 mm O/j—V2 m-)-
g. Check that the fuel pump is feeding fuel by loosening the
fuel hose fitting at the carburetor and switching on the igni
tion for a moment.
2. Should the engine still fail to start, check if sparks appear at
the spark plugs:
a. Remove the ignition cable from one of the spark plugs and
hold its terminal close to the cylinder block while the starter
rotates with the ignition switched on. A spark should now
jump the gap between cable and cylinder block. Repeat for
the other spark plugs.
b. If there is no spark or only a faint one, check that the igni
tion cables are properly inserted in the distributor cap and
ignition coil. Remove the cables and clean their terminals.
c. Remove the distributor cap and wipe it dry. Inspect and clean
all connections.
3. Sparks appear, but the engine fails to start although fuel is
properly fed to the carburetor.
Check that the carburetor jets and ducts are not clogged.
Clean the carburetor if required, see figs. 6 and 17.
