Harmonic pulsation / Vibration?????????
How does one check the "clocking" ? That has promise. But I thought there was really only two ways to put each yoke on and that it made no diff. ??
I was looking at the "rotor phasing" post again and still cant figure that out.....the line on the rotor as viewed thru a hole in the cap would just show the timing of the rotor going past the wire tower and when it fires...which is what you re adjusting when you adjust timing. How is this different from "clocking" the rotor?
From what I have read and learned ( not an expert) when you phase the rotor, you are aiming for the rotor to be aligned or very close to aligned with the cap tip whenever it fires, when timing is not advanced, it will be at one position and when it is fully advanced, it will be at a different position.
You want those 2 points to be equally close to the cap tip( probably will be on either side..
When I made a reluctor position change, I had made it worse, the rotor was well beyond the tip when it fired, at all advance positions. So it was out of phase. Now it fires right around the tip which I believe is the proper phasing.
340 dave... I am changing my exhaust... over the next week or so, trying different mufflers, and will let you know if it makes any difference.
Ignition wise, I also found I may have had a weak alternator and changed that at the same time as replacing and re wiring my voltage regulator to properly use "remote sensing".
Before my voltage guage was almost always showing 14.5 or so volts , but a fast flickering of the needle and the lights flickered quickly.
With the regulator and alt change.. NO MORE FLickering!!
The vehicle also seems to run much strong ( seat of the pants feel). Gotta test it some more but I think the pulsation I have been feeling is reduced/or gone.
Not sure but perhaps week alt / poor regulator might have affected the ignition??
I run HEi Module and msd blaster 2 with full voltage(no resistor)
I also used to get an intermittent stutter at idle.. and that also appears to be gone.. I think MY old Alternator was going--lots of volts, but perhaps not enough amps..
Sorry for the long one, but thought I would update on some of the items I have changed and am working on
