Help butane pronlems

[mark0491]

Hey i just hooked up a BBQ lighter butane attachment up to the office gun of destruction and every time i fill my chamber with butane and try the peizo igniter (also salvaged) i cant get it to fire. When i fill my chamber the piezo stops working, although when theres nothing in the chamber i have a steady works everytime spark ........ help me. PLZ :kermit: even Kermit wants an answer.

maybe you got tomuch fuel in it..

and maybe its to wet inside. I had this problem to, because the cucumbers.
There make my whole chamber wet, so there where no sparks..

You are probably putting too much butane in your chamber for ignition. Combustion requires a lot of air, try putting less butane in your chamber and venting in between shots.

1. Try a smaller spark gap. The breakdown voltage of air changes a bit when there is butane or propane present. You really only need the tinyest of spark gaps, a bigger gap does nothing for the gun's performance and is more likely to work sometimes and fail other times.

2. The generic answer for a combustion not firing is too much fuel in chamber. The combustion range for butane in air is ~1.9-8.4% by volume. If you are outside the combustion range then the fuel won't ignite regardless of how big your spark is.

3. Got a chamber fan?

yeah you know... this green dildo thingy you can eat






ill stick it with to much fuel

my suggestion is scrap the butane go for propane. butane has a tendency to be fiddly in minis. or use mentholated spirits.

Try venting it for an hour, and then put VERY LITTLE fuel in.
I think you got too much fuel.

A rule of thumb is that when a combustion doesnt fire coz of fuel problems, you got too much fuel, never too less.

I dont know how small your chamber is but on mini guns it can also be useful to spray little fuel in, dont close the cap yet, wave it 5 times forth and back to let a part of the fuel out and some air in. And then close the cap and fire.
