Dont worry, I had a bubbler, and the first time I pulled the rope the puppy blew flames in 4 diff directions out of the air filter and blew the bubbler all to hell!
Next time adjust your timing to TDC before running off straight HHO. Hydrogen has a near instant flash point and needs the plug to ignite when the pistion is all the way at the top. If you keep a gasoline timing then you will backfire like crazy.
I tried a lot of different timing points only to discover a setting very close to stock worked best. A flashback occured when I over fueled the engine. when the intake valve opened there was still burning fuel in the combustion chamber .
You can do it, it looks good, don't quit, we're proud of your efforts and I'll be checking back on your progress with the world. Small engine create a lot of polution, your findings are important for all four stroke engine mechanics. I don't have video yet so I cannot contribute, but I am a jet engine mechanic and know fuels, I've also built $500,000.00 custom hot rods from time to time. It's the calm before the storm, gas will go up, so I say "Get'er done", I'd give my left lug Nuts for hho
Thanks for the encouragement. I haven't had time to work on this lately as I have gotten married, moved and now have a farm to care for. I have tried different timing as you mentioned by relocating the flywheel and stock timing seemed to run just fine after all. I think the problem was I was using no outside ambient air at all and the fuel to oxygen ratio was off quite a bit causing an incomplete burn of the hydrogen gas and when the intake valve opened and supplied oxygen to a combustion
chamber still containing some very hot unburned hydrogen the flame front traveled in the direction of the oxygen supply which just happened to be the fuel cell. At the time the fuel cell exploded blue flames were spewing from the exhaust quite a distance which indicated an incomplete burn to me. Well thats what I think anyway. I have a much better plan for the future so check back. It might be a while before I get time to work it out as I have a lot of other work to do first on the farm.
HHO! if it burns in a torch, used in rocket fuels, and burners, then it burns much faster than gasoline. Pop out the plug, find top-dead-center... and mark the Flywheel. measure in degees from that "TDC mark" to the magneto magnet from the Center of flywheel. Reduce the degrees by pulling the flywheel and relocating it on the splines until you get normal engine speeds. Back-fire occurs when the valves are open during spark ignition. Rotating the "cam" gear one Cog might be a last option. Timing.
It was not becuase you had no bubbler it was bucuase your timing is 10-15 degrees advanced!! If you retarded to timing 15 degre back you will see no explosion and the engine will SPIN UP!!! SMOOTH!! Trust me I have dont it it works GREAT!! Great job by the way!!
It ran great with a higher air to hydroxy mix before this run. At that time the carburetor was still on with an empty fuel tank. I just wedged a pice of tubing into the carb and taped it sut around . there was still a bit air mixing through the gasoline circuit in the carb.I tried different timing setting and it ran best at stock timing for me. I haven't been working on it much as late . I got married and had to move. I'll get back to it though , I have some ideas I want to try.
my neighbors are used to it ... small pieces of PVC debris litter an area about 150 yards from the spot where I do my tests ... since getting a proper flash back pressure relief the problem is greatly reduced ... but the neighborhood dogs bark a lot when it starts sounding like I am doing target practice in the back yard ... backfires are normally over lean mixture but on some engines, can be a waste spark issue ... 5 parts air to 1 part HHO seems to be the sweet spot ...

very nice/interesting set up. I wonder if you could attach a small alternator to keep the amps up on the battery.

poor fish no home they make smaller batteries that hold more power then that fat baby. good video good luck i love to tinker to

the battery was plenty big enough. I got a little carried away with electrolyte and over fueled it.

Engine ran until the volume of gases increased beyond the ability of the engine to digest it.

can't you use a smaller battery
kc03300 3 years ago
why would I want to? actually the larger the better.
mymessagetomark 3 years ago
just to save weight . your right on the bigger is better though.

mymessagetomark, we win some and we explode some, but we will not stop doing what we do. great work sir, your franken mower is beautiful to me..

haha you fool, get that bubbler installed and get a video of it running. shame you didn't catch the explosion on cam. keep it up mate.
