Paul,

 This item is apparently  a small magneto.  It says it works up to
 15,000rpm.  Perhaps it might help in powering the 555 system.

 Looks exactly what the doctor ordered for carb or 555 EFI.

 Good work Doug. Thanks. Cheap too.

Paul, Doug -

I was interested in the "magneto" that you just brought up.  (See link
below in original message.)

Noting that "PCC Motor" was nearby in Pomona, CA, I stopped by today
to have a look at the unit.  PCC Motor looks to be your standard
Chinese import company that'll import anything they can resell.  (Just
my impression.)

In discussing and examining the unit there with Aaron Chen
(909-469-2454) he informed me that this was an inexpensive version of
the Japanese "Kitaco Inner Rotor Kit".  I found the Kitaco's all over
the internet, but here is an quick link to just one outfit selling them:
http://tboltusa.com/store/product_info.php?manufacturers_id=16&products_id=33&osCsid=a4542c0cd0a7721c3785160aa20534c7

The Kitaco looks identical to the PCC Motor unit I saw today.  I'm
going to guess that it's the same manufacturer as Kitaco's unit, with
the very-ethical-Chinese-manufacturer modus operandi of selling the
exact same production units on the side.  And at $45 vs. $180, it's
quite the deal.

Here's some notes for whoever wants to consider this further:
- The unit is small.  I'd estimate the mounting disk to be about 5-6"
in diameter
- The unit is easily disassembled.  Someone could easily remount the
coils on a new plate, say, on the old 13B distributor stalk  :)
- The rotating magnets (pictured in the center with the keyed shaft-
hole) have a TAPERED shaft-hole
- The unit's features include a "stop switch" ... handy
- Timing is adjustable (but it only looks to be SLIGHTLY adjustable)

The talk on the internet is that these are harder to start due to
slower magnet speeds, but are fine at running speed.  Also, they are
great for taking rotational momentum off the crankshaft for faster
revving.

I could pick one up if anyone wants to play with it (or you could
order direct).  At $45, it is a cheap experiment.  At least it's
readily available, and easily modifiable.

Back to the PWM EFI Pump Controller ...

I was thinking if the magnet were made larger in diameter it might work
better at lower rpm.
