Sounds like it's 180 degrees off on the timing. Make sure you are setting TDC on the compression stroke and not the exhaust stroke.

8-10 is usually good for most engines but it depends on your setup some can go as high as 15 but 8-10 is a good place to start

I need a new timing light I think. Set up and running nicely, (before the hub issue) with the vacc removed and pluged, at 800 rpm I'm showing 40* on the adjustable light 111!!!

I got one like that too. at all in it shows ~60 degrees 111!!!
