No, but I read somewhere you can use tweezers to remove the core.

side note: just got in a little bit of trouble with my parents, hope it doesn't effect this build scheduling.

Guess what I got

And my fuel port

1.8T metal cap works good.

So I tried it out again, 24.5ml of fuel in the schrader valve (got the insides out with a tweezers), hit the fan for 10 seconds. Using 2 big 6volt batteries for power. Hit ignitor, went off first try. Only problem is I guess the projectile is to tight as it still didn't leave the barrel. It defiantly sounded more powerful though.

Yes, several. Visit an auto parts store. They come in several styles including valve caps with a core tool built in. The valve caps won't reach the valve in propane tanks.
