I removed the top of the carb and cleaned out the inner screen. Then I fired it up and it screamed a bit, then started missing and died again. Then it would not star at all even after about 100 pulls - I felt stupid.
I checked for spark and the spark was really small and week, so I pulled the magneto, and noticed the the lead comming from coil that is riveted to the plates, was kind of loose and that the coil could slide up and down along the plates.
I crimped the rivet hard to tighten it up and then solderd it to the top plate.
Problem solved!!!!! fired up on the very first pull and ran super!!! without missing at all.
Now I gotta reset my fuel/air ratio and idle since the electrical is now really strong.
Funny though a few days ago, my kill switch failed - I had to pull the magneto and solder a brand new ground wire on and install a new connector.
My bike ran really well and consistent for the last 2 months and now ait will run great right till spring.

I bet it was those gound hogs, there awakening and go around widdeling loose ground connections.
But really, I have a Briggs and they use screw/machine thread and nut with external tooth starwasher. The thing that is really a mess is the solid wire that is very brittle for the kill switch/points that broke off on me right down next to the epoxy (primary larger diameter wire thankfully). I melted with a crummy old solder tip to gain access to a 1/4 inch of this coated magnet wire. Then exacto knife scrapped away insulation and the soldered using the good tinned tip an extension wire. Used High Temp RTV and had it all back together using stranded high temp wire like the stuff for volt meter probes. No breaking that way!
I just have to add this.... once happened when a ground wire on the blower motor on the air conditioner in car had got loose. I had a cloud starting to rise from below the passenger side floor under the dash board. I was driving freeway speeds and was freaked out. It was really an opaqe cloud expanding upward. The installation on the AC was not good. They did'nt use an external tooth start washer on the wire lug or even scrape away much paint to get a good ground. Just letting you know if you are not driving through fog, but are actually transporting it
