hybrid fuel help!!!

[spudmaster]

ok...i made a few hybrids..ive made them before i knew they were called hybrids..but this latest one i made will not fire at all. it just makes a funny little noise "poiiiing"
haha, i kno i have enough spark, im using 110 house current with something i nicknamed a burst wire. this set up lights up the entire combustion chamber even without fuel. my chamber is 103 cui and at 70 psi i need a 9 inch by 1/4 meter pipe, this thing used to fire when it was cold out but since the increase of temp im getting nothing i was wondering if i had the wrong amount of fuel im at a loss right now...i was also wondering if it had anything to do with the fact that the inlet of the propane is in the front of the gun and the spark is in the back...please reply

Hmm, if you are using propane, the fuel will mix rapidly throughout the chamber. Obviously no problem w/ ignition (lol, you're insane dude, I blew up a voltmeter and a GFI outlet in the house testing a similar ignition...) I'd say your guess is right, and that you need more or less fuel. How do you measure it out? B/c if you just use xxx amount of time with the valve thus far open, the amount you deliver will vary w/ outdoor tempterature.
