 Klaus told me any good ignition system can start paper on fire.

 Here is a video.

 Hi Paul, Can your new ignition system work on a radial?? I've a
 warner 7 cyl that needs help.

 cheers,

 Yes.

 What is the firing order?

 You will need 7 Lamar photo interrupter triggers and a small disk fastened
 to the crank shaft with holes in it. One photo interrupter trigger
 for each cylinder. Then you will need 14 Lamar ignition system on plug
 units. One for each plug. Gets expensive but highly redundant and
 reliably.


 Or you can build simple distributors out of plastic tubing
 with one Lamar ignition system on plug for each of the two groups of plugs.

 These would replace the mags and work like them. We are building something
 like that for the Chev small block using a stock Chev distributor.

 This is the cheap way to go if you can machine parts.
 You would be making two 7 cylinder distributor caps out
 of large dia. PVC pipe.

 It can also be done with a micro computer which would
 be cheaper in terms of trigger hardware but requires some
 programing. Are you willing to learn BASIC?

 I can give you guidance and help.

 Basically the ignition program is the LED blink program with a few changes.
 Don't get over whelmed by the Arm BASIC manual. You will
 be using only about 5% of it. Learn just the instructions you
 need to do what you are doing and ignore the rest.

 It is very similar to QB and that I can email you. It will
 run on Windows XP or Windows 7. You can use that to
 become familiar with the BASIC language.

 You would still need 14 Lamar ignition system on plug units.
 About $2800.

 What sounds the best to you?

Hi Paul

Firing order is 1,3,5,7,2,4,6

Yes, I can learn Basic. I wrote fortrand, Pl/1 and Cobol for a few years, then Assembler, the Pl/.SQL for many years...

cheers,

Russ

No computer.

I have given this a lot of thought. The best way to serve 14 spark plugs
is the same way they do it with magnetos. Basically we design a distributor
that fits the magneto mounts and has a disk with holes in it just like the
Lamar Instruments Modified Chevy distributor except with only 7 spark outlets.
Two distributors with two Lamar Instrument ignition systems.
