Why isn't my potato cannon igniting?

[Shawnturner]

Hi,

I can see a spark, but can’t get it to ignite. I have tried using hairspray and Lysol, and have tried different amounts of both.

I also tried wiping off the screws for a better spark (which actually seemed to help, but still no ignition.)
Please help.
Thanks!

I didn’t find the right solution from the Internet.
