may be necessary to achieve the proper rotor position. The distributor
collar should sit completely flat on the intake manifold or block.
Turn the distributor housing so that the rotor aligns with the housing as
5.
it was aligned with the removed distributor.
Install the distributor hold down and tighten the hold down bolt slightly.
6.
Remove all paint and corrosion from the distributor hold down for prop-
er grounds.
Place the distributor cap onto the housing. Tighten the cap into place
7.
and install the spark plug wires in the proper firing order. The orienta-
tion sequence and locations of the spark plug wires are the same as
with the removed distributor cap. It is easiest to move one wire at a time
from the removed cap to the billet cap.
FINAL ADJUSTMENTS
Start the engine and set the initial timing. 1.
For Vacuum advance distributors: 2. Locate the vacuum hose that was
previously attached to the vacuum advance canister. This hose should
originate at a ported vacuum source. Temporarily plug the end of the
vacuum hose at the ported end of the hose. Set the timing per the
OEM specifications. Securely tighten the hold down bolt. Remove the
vacuum plug and reattach hose to the vacuum canister.
WIRING
The Flame-Thrower III billet distributor can be used in conjunction with most
ignition coils rated at 0.32 ohms or greater. For optimum performance we
recommend our Flame-Thrower III canister style or HC e-core coil.
Many vehicles came equipped with ballast resistors or resistance wires. To
achieve optimum performance we recommend removal of these compo-
nents. Determine the proper wire length, and attach the provided terminals.
(Use a wire crimping tool to achieve an adequate connection).
Attach the 1. Red wire to the coil positive terminal or a 12-volt ignition
source.
Attach the
2. Black wire to the coil negative terminal.
Check to insure correct polarity and that all connections are tight. 3.
Reconnect the battery negative cable. 4.

INSTALLATION OF ADVANCE LIMITERS
The Flame-Thrower billet distributor comes with three different sets of
advance limiters. These allow the maximum mechanical advance to be
limited to 20, 16 or 12 degrees.
Choose the desired advance limit from the chart below. 1.
Remove the distributor cap and rotor. 2.
Remove the advance springs. 3.
Install one advance limiter on each inner advance pin. (See Figure 1) 4.
Reinstall the advance springs. 5.
Reinstall the rotor and cap. 6.
The advance limiters can be mixed resulting in unique variations of the 7.
original advance curve. When combined with mixed advance springs
and limiters the mechanical advance can have a maximum of 78 differ-
ent advance curves.

For Non-vacuum advance distributors: 3.
Remove the vacuum hose and plug the vacuum port. Set the timing per 4.
the OEM specifications. Securely tighten the hold down bolt.
MECHANICAL ADVANCE ADJUSTMENTS
To adjust the mechanical advance curve, select the appropriate springs 1.
from the chart below. The Flame-Thrower billet distributor is factory
equipped with the silver springs.

REV-LIMITER SETTING PROCEDURE
Remove distributor cap and rotor. 1.
Turn the ignition key to the ‘ON’ position. Do not try starting the engine. 2.
Turn the Rev-Limit dial clockwise until it stops. Turn the dial counterclockwise until it 3.
stops. A slow blinking of the LED indicates that the setting procedure has been initial-
ized and that the Rev-Limit can be set.
Turning the dial clockwise sets the Rev-Limit. After turning the dial, pause and watch
4.
the LED for verification of the Rev-Limit setting. Long flashes indicate 1000 RPM’s
and short flashes indicate 100 RPM’s. For example, 6 long flashes followed by 2 short
flashes means the Rev-Limit is 6200 RPM’s. Continue turning the Rev-Limit dial until
the desired Rev-Limit is reached.
NOTE: Leaving the Rev-Limit dial in the full counterclockwise position disables
the Rev-Limiter.
Let the LED sequence thru at least three complete cycles. This verifies the correct set-
5.
ting and prepares the unit for permanent storage of the Rev-Limit.
Turn the ignition key off, this signifies to the Ignitor III that the Rev-Limit procedure is
6.
complete. Note: The Ignition key MUST be turned off or the engine will not start.
Your rev limit is now set and will not change until you go through this procedure again. 7.
Re-install cap and rotor. 8.
NOTE: Setting the rev limit may be done effectively and easily on a bench or table.
Connect the module to a 9-volt battery as shown in figure 2. Then follow the setting
procedure outlined above.
