Just for added info for those who may not know

I am a mechanic and here is some info on psi

Running psi is much lower than you think

If you pressure test a v8 engine say u get a total of 145 psi

Running psi would be around 65 tops, so it is not needed to have 100psi spark, not that it would hurt just letting you know that when an engine is running the psi is lower then when u do a compression test.

@Park34
I think that was a very useful input info.
For you, what would it be a good psi measurement for a mono cilindric engine like we are testing with?
Running it manually at high rpm? maybe with a drill?

@xbox
Also, you might want to use a socket on a drill to start your motor....its going to kill your arm...LOL  Wink
I thought about that. I used a drill on previous engine but... you lose the FEEL of the engine starting.
It has his down side.

I still need to see more positive results on video like cap70 did. I hope that what kept me from doing it myself was the wrong engine I had for this.
If my engine tries to start like cap70 did... I think I will quit my job... just kidding
But you got to agree with me a engine running on tap water its so amazing that is hard to believe.

@Capacitor70
I'm not saying with this that I don't believe you. I believe in you because since the very first day I sow your video and contacted you have replied and been very helpful to me and all of us here.

I am not sure but most engines need atleast 80 psi to fire a run properly to begin with, so i would say anything that sparks at around 60-75 psi should be fine on running compression, may also explain why s1r says it takes a few turns over to get it to fire, typically the first stroke while doing a compression test is about runnning compression, otherwise if u take the valve out of the compression tester (looks like a tire valve) and start the enigne. (obviously a car engine) u will see running compression

Hello all,
No way for me with the lawnmower engine :
Not enough compression (I think) because of lateral valves, impossible to get +ve : I'm on -ve plasma, and not enough rotation with the hand launcher (hardly 2 to 4).
I tried with the factory carburetor, another one with choke, and like s1r9 with a reversed bottle without hole below (I remoded the carb in this configuration).

The engine never started

So now I'm looking for a 125cc 4 stroke from a motorbike, like cap70's one (with kick or electric starter).
