direct propane rules, its got to be the most reliable i think, mine fires perfect everytime.

i had an old bbq igniter that was already about to break, it flew outa my hand and hit the ground and the button flew out and the plastic broke, it was off a grill i had for about 5 years, i didnt have it on very good

if you wired it with electrodes the way you're supposed to, i dont see how it could have broken, but anyway, reguarding fans and aerosols, just use a smaller fan on a post mount, there is a pic of one inside a chamber on burntlatke.com under the build section

i just built it and the one wire was wrapped around a screw and the other was broken off the igniter and i twisted it back on, it was pretty rough

i dont have a choice about a smaller fan i ,ripped out of an old computer, im 14 and have no mode of transportation, would it help if i had the fan on and sprayed the axe in?

hm, i dont know, alot of the axe might stay on the fan, you could always tap a hole in the chamber with about 1/4" NPT (double wall) and spray your fuel in, then put in a 1/4" pipe plug
