I am a nurse.... So obtaining a syringe isn't a problem! Dumb question though. When "loading" the butane, can I just squirt it in the chamber then close the lid? Or do I have to have some type of loading valve?

I would need a huge syringe? Chamber is 4" x 18".

I am loading first. I will work on pics n
Tomorrow. Thanks!

Built my first gun. Using starting fluid. Has huge bang and nice flame, but when put the potato in..... NOTHING! I have tried everything. Less fuel, more fuel, bigger spud...... fires fine without ammo, but nothing with it? Help?!
Oh. I also tried hairspray, same result.....
