Can you stick +10 needles in the chamber to have a multiple ignition combustion? The needles would all be wired together and would be connected to a high voltage stun gun. Would I need more fuel? It would allow shocks in more areas of the chamber as stated in this link.

congrats, you've just thought up a cannon with multiple spark gaps (all wired together in series, of course)

its a good idea though, not sure how well needles would conduct electricity though

they use this method of ignition in hybrids sometimes.

I use that method in large chambered guns because it performs much better.

iv got 2 sparks with a bbq ignitor it does ignite better (when electrodes are clean)
