@HV:
I know your new jig is larger, more volume and you said it was leaking air.....
My last vid was with the old jig, the one that leaked was the old jig, it leaked because of the bolts in the side....MY new jig is much smaller. I made a new one because i needed a 3rd port for adding air. The original jig had 2 bolts taped through it to make the spark gap.

Have you done more pressure tests??
Not yet....

Is the jig still leaking??
yes...but i made a new one, so now its not....LOL 

Were did you get your adjustable spark gap......

The marine spark plug does not provide the same power a 2 bolts ground to points (pointing at each other) With the marine plug in the jig and about 30psi, i get very poor results. So i will drill and tap the new jig and try the 2 bolts again...in the new jig

@xbox,

I think building a test cylinder the same size as ( or close ) to the test motor you will be using after the circuit is perfected,  this would give more accurate test results.........just a thought , since you will not be using 2 ss bolts in the motor, do you see a good reason to proceed in pressure testing using bolts???

What makes you think i wont be using them in the motor? 

Yes i see good reason....PROOF OF CONCEPT! And i just fun!!! The marine plug and a normal plug did not have the guts to move the gauge a few psi...the bolts was 40psi +.....do you see a reason not to continue using SS bolts? Soon i will try my hand at making my own plug.... it will look kinda like this....



I didnt want to go the rout of making a plug.....but i guess i might just try one...or even a firestorm.

I have many other ideas in the works too....we will see what the best direction will be....

@Xbox,

I see... That makes perfect sense, please proceed ......What size and make of engine will you be using to conduct your trials after circuit is complete ??  .............Do you think it is appropriate to have a test cylinder close to the size of the motor cylinder that you will test the completed circuit on???

  Best Regards,

HV

Its a B&S 14hp  i think....the new test jig is a 3/4 Tee fitting, so the volume of that is the size of the jig. I am not sure as to the volume of the head of the B&S.............
