Recently got this saw(my first) and I had it running but it would not
idle. I adjusted the low speed screw but was a little heavy handed,
turnrf it too much and flooded the engine. I let it sit for the night
now I can't get it started at all. I get the pull cord out a foot and
it snaps back HARD. The compression has gone way up and I am at a
loss. Any help would be appreciated.

This is just a guess, but maybe worth a try. Sounds like you may have
a little bit of liquid gasoline in the cylinder. The
incompressibility of even a couple of drops of liquid would raise the
compression ratio quite a bit and leave the air-fuel ratio way too rich
to burn. Remove the spark plug and pull the cord several times to
purge the cylinder. If you have compressed air handy, blow a few shots
of air in the cylinder to dry things out. Then replace the spark plug
and try to start it.
