This car is my daily driver so I need to get this work done here. My gut on all this is I still do not have enough mechanical advance. I could be wrong. The 1 time I plugged the vacuum advance and gave it 20 degrees initial it ran so much better, it was running rich before rejetting and this is when mileage really fell off. If I go to a 1101 carb does Will have the manifold adapters, I understand his parts inventory is limited. I do not expect a high performance engine just make this run as efficiently as possible.
wait, you are running mechanical advance only? that could be part of your problem with fuel economy. that and teh richer jetting. the vacuum advance is there to improve fuel economy at part throttle.
