I enjoyed your lecture, you seem to have a pretty good handle on the process and operation. I heard a clunk when you closed the lid. I'm sure you have a future gasket in line for the lid. You answered my question about how the air is fed to the nozzles. I like the preheat idea. I zapped a vac hose in an instant also when I started out, it like instantly disappeared
Keep at it, you're hooked now. I started out pretty much as you did and just kept reading, experimenting and refining things. You might be able to get a little insight or inspiration from my early stuff. I got into posting a lot of details of how I did things. Go to the Small engine section and scroll down to "My first small engine run". Click on the titles and the page will auto jump there. You've got some nice flame colors also.
Good luck, Pepe

In particular, "My FEMA gasifier, build and demo".Ammo can @1:49-2:04 and @2:09-3:01 for a couple of tips on saving the rubber gasket in the ammo can.
PS: When you install the ammo can, make sure the hinge pins are pointing up.
