Hi Marshal,
Welcome. I don’t pretend to be a great brain in gasification, but I will say its not that hard to just get an engine running.
I have this ancient Gillette 3000 watt generator. I finally made something out of an old pipe.
The one thing I did right was learn to make good charcoal first. My neighbor has a decripit old apple tree that he said I could have all the dead stuff from just for cutting it off and getting rid of it. So I started making charcoal for my barbque. I make pretty good charcoal if I do say so myself. I have learned to make and use TLUDs. The first time I went and stupid lit it from the bottom. Then I went back and read where it said Top Lit Up Draft. Duh. The main thing is these things need is DRY wood. Not hard to find here in Colorado, but people in other climates seem to have more difficulty.

You can see here the burn has progressed about one third of the way down the TLUD. This is the tank from an old water heater
