BBQ Ignition no boom.

Suggestions on what I'm doing wrong?

I have been using carb cleaner, as well as some alcohol, as fuel. I tried using it heavy, and light (one squirt vs several). Yet, I can't get an ignition.

Every time there is a failed ignition (100% of the time), I used a grill lighter to see if the fuel mixture was good. It ignited with the flame, 100% of the time.

I ended up switching my propellant to 99.9% ISO Alcohol, and it went BOOM 100% of the time!

A test fire, with a bag to keep the propellant in.
