I'm at work right now and i just made a mini out of a small pill bottle and a bic pen and holy crap this thing is nuts... I never thought i would make one but i'm glad i did. This thing is super powerful but i'm having fuel problems. I'm using static guard right now which is really good stuff but i cant seem to get it to fire every time. When i fuel it some times i gotta blow into it to get more oxygen in it. I cant seem to either get enough in there or im spraying too much and thats only a half a second burst. Anyone else had this problem...any other fuel sources?

If you want to vent it better, instead of blowing into it (which would cause A LOT to come out) just let is sit open or wave it around once or twice. This should work letting only a small amount release.

I hear that hybrids are more powerful than a mini...Is that true?

I've read some of your posts Danny, I hope your not being sarcastic...jk. Anyway hybrids are MUCH more powerful than Minis.

Oh and "Mini" hybrids are cooler again!Tip: Get a syringe and a can of butane.

To measure the chamber volume first you need to fill the chamber with sand then convert that into cu. in. then take the barrel and divide that by each grain of sand. You'll figure it out.

With minis, I can attest to the fact that you must be extremely precise with your fuel metering. If you are using butane or propane, get a syringe like Novacastrian suggested. Then, solve for how much fuel you will need if injecting fuel displaces air by solving the following system of equations:
(f/a)=R<sub>S</sub>
V-f=a
for f.
If f equals the volume of fuel, a equals the volume of air, R<sub>S</sub> equals the ideal stoichiometric ratio, and V equals your chamber volume. If you want, you can divide your answer by V to get your adjusted ratio, (which for propane is around 4.03%).

Use sand, it worked so much better for me than a syringe ever would, trust me.
Dude, how could you inject fuel accuratly with SAND? I've read some of your post and I think you might want to put some thought into what you say. Beleive me, your welcome here, but be smart.DannyGlover666 wrote:Use sand, it worked so much better for me than a syringe ever would, trust me.

Just count every grain of sand and you'll get the chamber volume.

Wow.
I haven't seen this level of sarcasm since... well... since ragnarok's last post
(Actually, I think danny has been lurking for a while and actually knows what he's talking about, but is just posting stupid stuff to see our reactions)

Did somebody ask how to get the chamber volume? Forgive me if I'm wrong, but I think this is about accurate fueling. BTW wouldnt water be a more accurate way to get the volume?DannyGlover666 wrote:Just count every grain of sand and you'll get the chamber volume.

But how does that inject fuel?
Counting sand is tedious and takes much more time than using the formula for volume of a cylinder.
Back to my original question: how does that inject fuel?
The thing is, the sand can't inject fuel. The syringe allows transport of fuel from its source and an accurate measurement due to the graduations on it's side.
