Where is the best place to place the sparking part of an igniter? Towards the end the the chamber, in the middle or towards the front.

Thanks

What about duel sparks.... and would a bbq igniter be capable oof doing dual sparks?

Also.. I have a T pipe at the end of my chamber and a chamber fan in the T..

Generaly, we suggest putting a single igntion point about 1/3rd of the way from the rear chamber wall [to the front of the chamber].
In reality, I suspect the ideal location is dependent apon projectile mass and chamber dimensions (among other variables)... but this will do.

As far as I know, there are no guidelines relating to the location of the gaps when using two sparks... and short of computational solutions, I don't know.
Just locate them at 1/4th and 3/4ths, I geuss. It may not be ideal, but the difference is likely to be small.
