I wouldnt worry too much about what to do or what not to do. Most of the people on here are hobbyists, working with whatever materials they have on hand, and the tools and skills particular to themselves. You will find that there is lots of cooperation here, but the path you go down is ultimately going to be the one that makes the most sense for you. Wherever that ends up being - take lots of pictures!
That said, if you can get a flare and keep it lit, you can run an engine. Next up is to decide what you are going to power - and engine size and desired run-time will be important considerations.
What sort of a nozzle did you build? Lots of designs have been tested, and there seem to be at least a couple of really successful ones.
Looking forward to seeing what you cook up (and I will also scour anything in the background of your pictures for interesting stuff) I like that sawhorse made out of iron pipe, and that table saw motor will be perfect for building a charcoal grinder!
Oh yeah, i almost forgot, welcome to the dark side
