ANY NGK with an R on the plug has a resistor   there are many that don't   Chet

im impressed with your vid.  Could you send me a quick sketch of your wiring and exactly how you hooked it all up?

I worked for four hours today trying to get a 10hp lawnmower running on gasoline so i could convert it to this system.

stupid me nearly smashed my thumb off between the flywheel and coil, hurt so bad i said nasty words.  Funny thing is that was my left hand, so stupid me, mad and determined continued to work on, bleeding and in pain, and wouldnt you know it, i done the exact same thing to my ring finger on my right hand.  This time i was nearly crying and sure i was gonna have to go xray my finger thinking it was broke.  So here i am tonight one finger typing this in agony WITH BOTH FREAKIN hands disabled because of this project.

What i have is a 10hp tecumpsi engine on a murray lawnmower.  I never did get it to run, i found out the intake valve is broke or the cam is broke.

Anyway, it will fire and im getting a decent "regular" spark.  I already have the 400 watt (800 watt max) inverter.  What would you recommend me getting next to get a decent plasma spark going.

I dont have any of the diodes from cap70 ciruit desighn yet, my radio shack is exactly that, a freakin shack, they have NOTHING.

Where and what do you recomend me getting next for the build.

@Capacitor
Hi, I'm trying to test your circuit, but got a couple questions:
6a10 and 6a4 diodes appears to be listed as 6Amp 100V as well as 6Amp 1000V
Same happen with 6a4 that I found listed as 6Amp 40V and 6 Amp 400V

Could you please clarify which ones do you use?
Have you discarded other similar rated diodes or any similar could do?
my electronics supplier must order them for me and it seems to be a big difference in price.


@all
I tested a few times the inverter capacitor circuit, but did not see too much difference with or without water, a big spark in both cases some melted plug when forgot to open contacts, but not too different when water added, as I`m following the charge-cap-discharge-through-by-hand it is difficult to me to see differences and maybe is not the optimal test procedure.

I will try to build a timer with a 555 to perform continuous adjustable sparks, and later try to add Low volts High current also adjustable in some way to try to find the best current on the bench and also, something that seems to been not tested, under high pressure in a compressed cilinder.
as I?m a little rusted in electronic, has anyone already developped such a test circuit?

Just some idea flying around...
This is supposed to be an open source development born after s1r success, who, as I understand want to share, as well as many other are sharing their ideas (maybe I misunderstood that?).
So, why does him not share, as so many people are doing, and only gives unclear ideas that seems to keep us looking around with so difficult research?? is someone keeping us looking in the not too correct direction??
well, maybe is just a stupid doubt, I`ll back to my bench... I have very little time to put hands on.

Best whishes
