EnDuraSpark Electronic Ignition

Installation & Troubleshooting v5.1

Cut out the timing wheel from the sticker sheet. With

masking tape, temporarily install the wheel so the pointer

lines up with the “OT” mark.

The timing degree sticker is only installed temporarily so

the dynamic timing can be checked. The sticker should

be re-installed every time the ignition timing is modified

(timing wheel rotated on its hub).

The ignition curve parameters of the EnDuraSpark Electronic Ignition are non-

adjustable. The initial static timing offset, 8°, is fixed electronically. The RPM that

advance starts, 1000 RPM, is fixed. The amount of advance is also fixed: 26° for stock

ignitions, 20° for dual-plugged ignitions. This results in a maximum advance value of

34° for stock ignitions and 28° for dual plugged ignitions. This is optimal timing for

almost all 1970-1980 Airheads, providing an advance curve not limited by emission

control concessions.

Adjusting the ignition timing is done by loosening the three set screws on the timing

wheel and rotating it the amount of degrees to be changed. This changes both the

dynamic “F” and static “S” points (since the difference between them is fixed).

Getting the fully advanced ignition timing correct is much more important than the static

idle timing. It is not important if the timing is off a degree or two at idle. Engines don't

ping at idle (unless something is drastically wrong). Since the advance range is fixed, we

set the advanced timing perfectly and let the static timing fall where it may, usually 8°.
