My altanator/ stator/ generator...what do I have here?

[basketcase]

But first, I hope you notice that I've updated my previous-post above with a master-graph & associated text ! _ As it should all well explain the pros & cons of the factory-set alt.timing vs. a good compromise-resetting option for your alt.rotor installation-setting.

I saw that, and under stood it. Hopefully others can learn from it too.

____ Great !
__ So did you get your alt.rotor set yet ?
And if so, what timing-setting did you finally elect to go-with, (the 27-degrees you last decided-on, or what) ?

Jimmy said he put it at 18 degrees like we talked about earlier. (I didnt get the change to him in time). The motor was all buttoned up with oil in it, so I will have to change it to 27 degrees myself.

____ I don't see much need to bother with changing that setting, cuz left that way means that instead of a 'compromise', the alt.timing will instead be merely optimized for the static-ign.timing (with peak-alt.power being produced 3 to 12 degrees* just before that. [* depending on set static-timing, of 5 to 8 BTDC]).
The only concern now is whether there'll still be sufficient power once engine-revs climb-up towards max.advance (near 3000-RPM). _ Certainly however, the ign.spark will accordingly weaken (along-with the weaker alt.power-waveform progression), at a faster-rate than the natural gain in alt.power-output (expected due to alt.revs building-up), can make-up for, by that max.advance-point. _ But if the ign.spark can stay adequate enough to make it up-to 3000-RPM, then it can only become stronger from that point onwards, (as revs continue to climb beyond that max.advance-point).
So with the alt.timing left as it's been set, you should still expect to obtain decent ign.spark (without a battery) at kick-starting speeds,, but I'd expect the ign.spark to fade-out as the auto-advance moves towards it's max.advance-point, (since the alt.waveform-pulse will then only be just 9-degrees* in-towards it's 90-degree 'peak', at that point). (* That's assuming a static-timing of 8-BTDC,, 5-BTDC would allow the waveform-progress to proceed up-to 18-degrees into the power-pulse, [rather than merely-just 9], [but even-so, that's still rather close-to next-to-nothing].)
__ You could now try checking to see if you can obtain ign.spark with raw alt.power (& without a battery) at this point-in-time.
And assuming that the spark is strong enough, you then may as well not be much concerned with resetting your alt.rotor-timing. _ Cuz along-with an added capacitor, it's then possible to save-up the previous power-pulses to become combined with the 'timed' pulse (for improved ign.spark at all RPMs) !

I will not be able to put the motor in the frame for a week or so. I have a trout fishing trip planed this weekend with my kids and a ton of estate work when I get back.

____ Understood.
Do you understand & agree why I've indicated that you need-not be too concerned about your alt.rotor not being exactly timed as optimally as I had LAST suggested ?
__ Also,, you haven't yet expressed any of your thoughts concerning the possible advantageous use of a capacitor. _ Do you understand how your project could possibly benefit from the inclusion of such ?

A capacitor sounds like a good idea.

____ Here are some links to such items, each with their-own text-explanation as to why their cap.unit is of useful-use for such as you ought to consider. ...

This last listed example -("Bat-Pac"), seems promising as being more than just a mere capacitor, (due-to it's description-wording concerning the included term "voltage" *), and-so may possibly include a voltage-regulating circuit as well. _ And if-SO, it could be quite a bargain if purchased for under 30-bucks delivered !
(* "voltage" , as stated within the following listed-claims - "The Bat-Pac's voltage output is better at idle, and more stable and cleaner at all R.P.M.'s "
"The Bat-Pac will supply the proper voltage to the electronic and electrical components that depend on the battery's ability to hold a charge in order to function properly, most notably the headlight."
"The Bat-Pac provides a more stable voltage than it's predecessor (the battery) at all R.P.M.'s." _ These claims would be fairly questionable for such an electrical-component if it were just a mere 'capacitor' -[which is a term that's not seen mentioned within the eBay-ad].)
__ However the other four examples near the top of this list, pretty-much all seem to be well overpriced by 200 to 400% of what they're actually worth, (as a simple/mere capacitor of these fairly appropriately sized units, ought-to retail for under 20-bucks).
__ You may possibly hear-tale from others who have discovered that capacitor/battery-eliminators don't really make such a very-good replacement for a good battery,, but those people more than likely had simply connected-up their chosen capacitor merely the very-same direct-way as if it actually was the same as a storage-battery, and so-thus directly-connected without including an added diode to prevent it's built-up charge from being shared-back to other sections of the load-system (rather than merely-just the ign.system-load, itself). _ So in such fairly-ignorant cases, a directly-connected capacitor can't help-out as well as expected, cuz it's temp.stored-charge can then be bled-off about as fast as it's compiled, and-so thus-then unable to provide it's expected-benefit (for merely-just the ign.system only).
So with a capacitor like these,, ya can only make GOOD-use of one, by simply restricting it's output to merely-JUST the ign.system ALONE ! _ That way, the engine will then be able to get started-up easier,, and THEN, become able to produce more alt.power for use by the REST of the load-system.
____ Your entire alt.power-system can easily be divided-up ('electrically', not physically of-course), into two to four separate power-circuits,, merely one of which, could be allowed to be dedicated merely to just the ign.system only !
__ If that last listed-item -(BAT-PAC) is actually such as that which it seems to be - (a MAJOR system-component like a 'Mity*Max'), then that particular-item would be a possible ideal-addition for good-use within your finished electrical-system.
(* A "Mity Max" is a rectifier & regulator & battery-eliminator, all-in-one unit !
[However I'm doubting that the "BAT-PAK" also includes any rectifier-circuit of it's very-own.] )
