My mini potato gun/spitball gun wont work! Answered

I have made a mini potato gun and at first it was working but it doesnt seem to be working. I spray into the gun then when i go to shoot it it doesn't work.

There is a spark and I'm definitely spraying enough aerosol so that shouldnt be the problem.

Im not sure what im doing wrong, can anyone help or make any suggestions ?

Too much fuel, not enough air. Start with a small amount. Work your way up.

Start with a small amount of aerosol. Try to fire it. Try a larger amount. Try to fire it. etc. etc. Until it fires, then you will know exactly how much aerosol is required. Too much aerosol won't work as the air/fuel ratio is too rich. You need the exact amount. Experiment. If this doesn't work and you definitely have spark, then the chamber is probably not air tight anymore.
