@Xbox,

Nice video of the plug under water, have you tried placing a heavy object over the plug after you fill it with water.
like Peter Graneau's experiments?

@Cap70:
I tried to go back to gas too, it didnt work with gas for me either.

@HV:
No i didnt...to be honest, i didnt even think about it...lol

with 125CC engine it gives blast sound on exhaust cycle, but not running the engine with gasoline....

Hi Cap70,

Sounds like your ignition timing is off?  S1r says spark firing should be 30-40 deg after TDC.

Also, do you have a waste spark (ignition coil firing every crank rotation)? That blast sound you hear is the waste spark igniting on the exhaust stroke.

xbox and capacitor,

im a little confused, you say its not running.  Are you saying its not running at all even with normal spark and on gas, or are you saying its not running on PLASMA spark with gas???

If it will run with normal spark and gas, i cant figure why it wont run with the plasma spark and gas.  Unless the plasma spark is being delayed slightly and its throwing the timing off to "after top dead center"

If i were you guys what i would try is to turn the timing back so it would hardly run with normal spark and then try it with the plasma spark and see if you can get the plasma spark to run with gasoline like this. 

Be careful, you can turn a small engine timing back far enough it will cause the engine to run backwards, i worked on a kawasaki racing 3 wheeler one time and we were goofing around with the timeing and finaly got it to run, and my buddy jumped on it, throwed it into gear, and it nearly threw him over the handle bars, it was running backwards and going in reverse  .  True story, and it ran good too.

@rfsimoes:
Sorry man..i thought you couldnt get it to work at all...lol 

Anyway, i tried my setup in an engine...here are the results...

-It didnt run...lol
-Spurattic firing (some times it was fine )
-Steam doesnt do anything...not even on the bench!
-The engine and chassis is LIVE....so dont touch it while not wearing shoes...LOL
-Could be a timing issue....its to dark out now to mess with timing

Now here is what i think rfsimoes and i have in common....it would seem to me that it will not fire under pressure!! I had the plug out and it fired every time the magnet passed the magneto or the pickup for the automotive coil. In the engine i can see the waste spark firing... it lights up the inside of the exhaust port. But i looks like it was not firing when it should have for the power stroke. Like it misses the power stroke fire and just fires the waste spark.

So now i will build a small PVC pressure chamber and put the plug in it and put some compressed air into it too.... and see what happens...

Now, not firing under pressure is kinds funny, because it will fire under water!!!! 

Hi xbox,

Yea, it sounds like your timing needs to be adjusted to 30-40 deg after TDC.

The waste spark sounds like problem when you have to charge up the cap and the cap cant charge up fast enough to fire on every stroke?
