You wouldn't need a hacksaw man. The valve is connected to a male screw on adapter so i can just unscrew it and put it in. I've working on setting up. I use starter fluid but i took the nozzle off it and put a different one on it because it makes a beter fuel/air mix. Yes, you do see two spark gaps ...

Hahah bro i don't have venting in it. next one will have it though. but yes i do use it for filling and it speeds loading&shooting up quite a bit.

Over the summer, i realized that a steady routine of eating ramen and playing Halo tends to get boring. so me and my Bros decided to make a potato gun. Check it out =)
