This part is easier. Using HIGH TIN solder, and RUBY FLUID as a cleaner you can solder the jet closed again. I use sewing needles to keep an opening in the jet (pilot hole as it were) Just use a smaller bit, and you can clear the solder by hand. I use an electric stove in the back room to heat the jet much like a soldering iron. One jet will tune your scoot w/ a little patience.

Start over from the beginning. Use a NEW spark plug to see if you have spark. Use indian shellac/permatex #3/ OMC perfect seal, to reseal all the gaskets. It sounds like you lost spark somewhere. Another thing that happens alot is when you pull the boot off the plg it will pull the wire away from the boot. Try unscrewing the boot from the wire, cut 1/2" off the end of the wire, and screw the boot back on. You want to see a bright spark.

found my problem. The bottom ring is stuck in the ring groove. So I am losing compression. I am ordering new rings. Will let you know how it goes when I get them in.

I've had that happen on my ZX50.  I just took some fine grit sandpaper and cleaned up the ring land and the ring and all has been well for at least 5,000 kms now.
