I'm having a bit of problems with propane, I've tried inserting anything ranging from 1 percent of the volume of the mini to about 10 percent, still none of the mixtures went boom, I did get a spark, does anyone know what I could be doing wrong?
*edit* oh yeah, I'm using an Afterbite stick as a chamber and a spark plug as the ignition source. |

| How did you measure it? Did you use a syringe? Mini are pretty tricky to get to work. |

| Your mix just isn't right. Minis are tricky, so make sure you vent well and measure precisely. |

I used a syringe yes, Maybe I need to remeasure it, or use a fuel like alcohol.
On another note.
I've already made a cool stock, pictures when it's painted. |

| For minis I have done is spray it in the air, then run the mini were you sprayed it in the air. It kind of works. What is the volume of it? |

Calculate its volume and then calculate how much propane you need at 4%. Figure out how much of the sytinge that is and Voila.
Buy the lighter refiler butane thingy works really good with them syringes. |

Right, the chamber was way to small, I needed less than a mililiter of propane, I got a larger chamber and it works now.  |

| Nice, glad to hear it worked. Did you calculate the right volume and everything? You should post it on minis. |

I have a mini of only 22cc and it fires every time with 1/2 a cc of butane, it shoots q tips approx 40 feet at an upwards trajectory of about 20 degrees.
Peace
