Installing a Dyna S - Timing

[posplayr]

Agree with Ed, also had a long discussion with Bill last nite on Dyna S timing; he used a degree wheel.

If you have a caliper you can measure the marks; they are for the 1-4.
T=0 deg
F=12 deg (12 deg of initial advance)
| = 32 deg (+20 deg of mechanical advance)


Total of 32 degrees should be in by about 2400 rpm according to the manual

You want to check the 2-3 initial advance as well. That can be adjusted slighyly with the little hex screws on the mounting plate. By using the degree wheel Bill measured total advance with both 1-4 and 2-3

Dan,

When holding the advancer you need to hit the mark to the right of the F mark - that's the one for when the advance is maxed out. If you don't hold the advance you can go to the regular F mark. And yes, you want the point where the light just comes on, not in the middle of the range.

I've done one of these before (about 3 years ago) & it worked fine but I figured I'd get some feedback this time.

Nothing really concise from the search panel so here goes...

The DYna S is installed & wired. On the 78 1000 you can just plug into the black /whites by the batter & take a new lead to tap into the Orange white which sits in that big rubber boot covered bundle in front of the inner fender.

So.....

Turning the plate anti clockwise advances, clockwise retards.

You are meant to static time it at full advance.

So the trick is to make the test light come on with the rotor held at full advance & have the 1.4 line line up with the timing mark on the case (actually it's a small plate but it's stock).

My question is this: Is it better to be at the point where they line up & the light only just comes on (i.e. if you were to reverse the engine even a tiny bit then the light would go out) or is it better to be somewhere more central in the range of where the light will light?

If my timing light is not playing up (think it got hot from the wires sitting on the radiator of my Falcon & it drove it loopy so hopefully it's recovered now it's cooled down!) I guess I will probably dynamically time it after in any case to see where I'm at.
