FINAL ADJUSTMENTS
1.
Start the engine and set the initial timing.
2. Tighten the distributor hold down.
3. For vacuum advance distributors, connect the vacuum hose to the vacuum
advance canister.
MECHANICAL ADVANCE ADJUSTMENTS
1.
To adjust the mechanical advance curve, select the appropriate springs
from the chart below. The Flame-Thrower billet distributor is factory
equipped with the silver springs.
2. Remove the cap and rotor.
3. Remove the existing springs and install the desired springs.
4. Reinstall the rotor and cap.
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.
1. Choose the desired advance limit from the chart below.
2. Remove the distributor cap and rotor.
3. Remove the advance springs.
4. Install one advance limiter on each inner advance pin. (See Figure 1)
5. Reinstall the advance springs.
6. Reinstall the rotor and cap.
7. The advance limiters can be mixed resulting in unique variations of the
original advance curve. When combined with mixed advance springs and
limiters the mechanical advance can have a maximum of 78 different
advance curves.

8. Tighten the cap into place and install the spark plug wires in the proper
firing order.
9. Locate the vacuum hose that was previously attached to the vacuum
advance canister. This hose should originate at a ported vacuum source.
For Vacuum advance distributors:
Temporarily plug the end of this hose to allow proper timing. After setting
initial timing the hose will be unplugged and attached to the vacuum
advance on the distributor.
For Non-vacuum advance distributors:
remove the vacuum hose and plug the vacuum port.
WIRING
The Flame-Thrower billet distributor can be used in conjunction with most
ignition coils rated at 0.6 ohms or greater. For optimum performance purchase
and install a Flame-Thrower
high performance coil.
1. Many vehicles came equipped with ballast resistors or resistance wires. To
achieve optimum performance we recommended removal of these
components.
2. Determine the proper wire length, and attach the provided terminals. (Use a
designated wire crimping tool to achieve an adequate connection)
3. Attach the Red wire to the coil positive terminal or a 12-volt ignition source.
4. Attach the Black wire to the coil negative terminal.
5. Check to insure correct polarity and that all connections are tight.
6. Reconnect the battery negative cable.
