Need help getting car to idle.

I cleaned the carb really good and checked out the PV. It started for a while, but still won't idle. I didn't get a chance to let it warm up completely to see if it will idle when warm...heres why.

It ran for a couple minutes, and I tried letting off the gas a little and it died. When I tried to re-start it, it kicked back and ran backwards for about 3 seconds, several revolutions. WTF?!?! The timing is locked out at 30* with a start retard of 10 degrees, so I'm pretty sure it's not the timing. What all do I need to check now?!? Could this have caused the timing chain to jump? Please Help!!
