Hard starting when cold

It's a 318 with a 2bbl It has the mechanical choke that moves with the manifold heat. I just adjusted it so that the choke butterfly is closed all the way when cold. It started a little better but still took a bit.

I checked the timing while the motor was warm idling at about 750 - 800 in park and it read 10 Before TDC. I forgot to pull the vacuum advance so I'll have to recheck it. The spec calls for 0 TDC.
