Thanks Everyone for you help so far
Here are the following things I will try based on your suggestions

1.. I will set the mixture screw on all 6 at 1.5 turn and adjust from there.
2.. I will exchange out 4.5 power valve to 3.5

3.. Different PCV valve.. perhaps current may not be the correct one.
4.. Advance timing to 25*

I wont be able to road test today as its raining heavy but will post with some photos today of the set up. I feel like I am close on this as it runs great with no bogging when I do WOT. Just issues of engine stall when choke is wide open at idle.
