Looking at the flame and the sound I get the impression the thrust was not great. More fuel and oxygen needed (LOX) and stand well back. Good to see this though as experimentation is great stuff. Give us the thrust please in Newtons and the Specific Impulse. Well I can work out the SI from the thrusts so if you can get a rig to measure it that would be super cool: a petrol rocket engine..wow.
Nice test. I've done some N20 and propane tests myself a few years ago. I too had short bursts until I knew it wouldn't explode. I later got to about a 10 second burn at about 20 lbs thrust. Didn't have good measurement equipment so not accurate. I'm thinking of posting my tests. I tried several chamber designs, the best being ablative cooled with graphite nozzle. I used a gun-powder pellet to start it. Is that what you used?
probably, make a rocket with two staged methods and you could use the liquid engine as its first stage as it has strong thrust and then weaker but long duration engine in the second stage..
it probably produces enough thrust to carry a huge fuel tank. just because it's only hooked up to a small fuel source for a test means nothing. maybe they don't want to waste nozzles on preliminary tests
By 0:03 I was like.. that sucked.. then it was OK.

great engine, lol I had the volume turned up all the way and it was fine at first then when it kicked on I grabbed my ears, lol

that surprised me with my headphones on high vol.

use liquid propane instead and make it bigger

except for the fact that it does not burn for a duration long enough to actually get decent height...

Just wondering where you got the plans for your engine from?

I designed it myself. I read "Space Propulsion Analysis and Design"
