Cap70: on your setup.... are you going to use a common ground to the block for multiple plugs, or are you going to use a wire at each plug base? Also thank you for all your hard work and posts! At least you not hiding it in a tuna can....

Apph Arrgh!  My ignition coil flat out BROKE OFF the engine completely today while I was running it on gasoline!  Wow, what a set back.  But it's not entirely bad news, this gives me an opportunity to find another ignition system for the engine.  But, the engine does run, and it runs well!  At least before the coil broke off.  Anyone know of an electronic ignition that could be fitted to a small Tecumseh engine?  I was thinking of whipping something up myself, I was going to use a hall effect sensor, a transistor, and a small doorbell transformer to do the job.  I don't know if the doorbell transformer will be able to put out the volts I need, however.  Any ideas?

How big of a coil?  Would one from a 24 v doorbell transformer secondary or primary be good enough?

Hey everyone....here is  new video from s1r9a9m9 !!!

LOL...he drinks the water!!! LOL  (some peeps thought it was gas in video 1)

ALSO...this is NOT my video and NOT my work, i am just passing on the info

are you going to use a common ground to the block for multiple plugs, or are you going to use a wire at each plug base?
I dont have multiple cylender engine, no multiple plugs

SuperGod
You need ignition coil or go for black and white TV flyback transformer.
flywheel >> magnet >> Relay Coil (hall effect) >> rectifier(for relay coil) >> transistor >> ignition coil >> HV

Again, I won't go into the other aspects, as in Cap types, instant current, and all that.  I'm
sure that you have been setting this up longer than I have, for this app
For this, I assume a waste spark, unless,
adjust values as needed to get the biggest LV pulse at the desired RPM.
In my video I observed many of the sparks are not visible, but it gives sound, capacitor gets discharged instantly, i need slow discharge to transfer enough heat.


DO NOT TRY MY LAST CIRCUIT WITHOUT TRANSFORMER, IT GIVES ELECTRICAL SHOCK TO ANY WIRE, INCLUDING GROUND

insterting coil in series with LV changed its sound to poof, and duration of plasma is much improved
