Hi Bulmfuz,

If you would drill and tap a small 1/8 hole betwen those two plugs, put a 1/8 injector tube in it, give or take, put a small nozzle/restrictor to spray it on the outlet, feed water to it with a high pressure check valve so water could go/suck in with the down stroke, but nothing go out on the upstroke, needle valve it so you could control total amount/stroke, I think you could have a very nice injector on that B&S engine.  I plan to do that on my next SMALLER engine.  You need solid steel or brass up to the check valve, then any type of tubing after that.

An injector of some sort is in the works but I wanna try it like this for now, soon as my diodes get here. I turned the motor over a few times with the choke on, no circuit hooked to it, then pulled the plugs out to look at them and the plug in the original plug hole wasn't very wet but the plug in the new hole was dripping wet, we'll see what happens in the next few days.

By the way, I love watching Marvin the Martian.

Hi RD,

I would like to commend you on this video and make a note to others that it is indeed a marble and not a foam ball that you are lifting with a water explosion. A marble does have considerable mass and requires REAL power to be lifted. Such video examples proving the proof of concept can only help in our endevour to gain awareness of this process in an effort to further it's development.

Ossie

Thank you Ossie, yes it is a real old time standard glass marble, I do not have the weight. I have access to a postal scale on Tuesday though. The metal cylinder chamber I used did not seal at the base of the plug so I would imagine some energy was lost at that junction. I would have conducted a few more experiments but I was booted out of the laundry room and had to dismantle the set-up prematurely. Such are the hazards of water plasma research  .

Regards,

RD

Inconsistent sparks could possibly be from high impedance causing the coil secondary coil to short to its core to ground.  Check that the HV lead is all the way into the coil, and the the resistance is low to the plug and the gap is not too wide.  One should never fire the coil without the HV wire inserted to a plug or to ground.  If you fire the coil without a HV wire in it, the HV will jump across the fine secondary windings to the core and burn its insulation.  Check the resistance of the secondary and see if it is less that you started.  Should be around 10 to 12k ohms.  If less, it could mean the secondary HV winding is shorting to its core.

A good plug and very good ground helps too. I was having trouble with consistent arcs out in the open til I changed plugs and grounded it real good.

It takes a few milliseconds to charge up fully.

Yes I see, I wasn't thinking along a time line but I understand now. 

@Retrod
Thanks for demonstrating the existence of real motive power.  It's something I've been hoping for all along in this thread, and is very encouraging news indeed.

Hi K4zep,

Isn't the operating RPM of the Fox 78 far higher than the burst RPM of the grinding wheel? Also, I've had great difficulty with severe vibration in similar high RPM setups.
