TROUBLESHOOTING
If the vehicle fails to start after installing the Flame-Thrower distributor;
Check to insure that all directions have being followed correctly.
•
Make sure that all connections are correct, and tight.
•
If converting from a point type ignition, make sure that all primary resistance is
•
removed from the circuit.

MECHANICAL ADVANCE
To adjust the mechanical advance curve, select the appropriate springs from the
1.
chart below. The Flame-Thrower distributor is factory equipped with the silver
springs.
Remove the cap and rotor.
2.
Remove the existing springs and install the desired springs.
3.
Re-install the rotor, Note: If the Flame-Thrower distributor is used in a high
4.
R.P.M. application, replace the metallic rotor retaining screws with the provided
Teflon screws and washers. Do not over tighten the Teflon screws.
Reinstall the rotor and cap.
5.
DISTRIBUTOR INSTALLATION
Disconnect the
1.
Flame-Thrower™ wire harness from the distributor cap. Remove the
cap from the distributor housing.
Install the distributor gasket over the gear, and up to the distributor collar (gasket
2.
not requires on Oldsmobile application). A small amount of gasket adhesive will
help to hold the gasket in place as the distributor is installed.
Lubricate the
3.
Flame-Thrower™ distributor gear with a liberal amount of engine oil.
Turn the distributor shaft until the rotor is in the same position that was noted with
4.
the old distributor.
Place the distributor into the engine. As the distributor drops down, the rotor
5.
will turn as it engages with the camshaft gear. Adjust for this rotation by turning
the rotor a few degrees prior to the gear engagement. Several attempts may be
necessary to achieve the proper rotor position. The distributor collar should sit
completely flat on the intake manifold.
Set the distributor cap on the distributor housing. Turn the distributor housing until
6.
the number one terminal on the cap lines up with the rotor. Fasten the cap to the
housing.
Install the distributor hold down and tighten the hold down bolt slightly. Once the
7.
ignition timing is adjusted the hold down bolt should be tightened completely.
Starting with the number one spark plug wire, move the spark plug wires from the
8.
original distributor cap to the Flame-Thrower™ cap one by one.
If converting from a point type ignition, new HEI style spark plug wires should be
9.
used (Check with your dealer for the Flame-Thrower™ spark plug wires).
Connect the
10.
Flame-Thrower™ wire harness and vehicle wiring into the distributor
cap.
If converting from a point type ignition, remove any resistance wire, or ballast
11.
resistor that may have been previously used.
If a resistance wire is present: replace the wire with a 12-gauge copper stranded
•
wire. Most resistance wires begin at the engine compartment side of the fuse
block.
If a ballast resistor is present: remove the wires attached to both sides of the
•
resistor. Connect all of the wires removed together at a single point. Isolate the
connection from any grounds.
Plug the Ignition switch wire into the position marked
•
BAT on the distributor cap.
If a tachometer is used: Connect the tachometer wire into the position marked
12.
TACH on the distributor cap.
Re-connect the battery.
13.
Check to insure that all spark plug wires are secure and in the correct place.
14.
Start the engine, and check the base timing.
15.
Check the vehicle manufacture specifications for the correct timing. Rotate the
16.
distributor housing to achieve the indicated timing specifications.
Once the timing is properly adjusted, turn the ignition switch off and tighten the
17.
distributor hold down.
