Question on MSD distributer
 

In traffic motor acts like it's missing cylinders. Fuel flow is good.
Could there be an issue with MSD ready to run distributer.?
I have been trying to fix this issue for a very long time.

This is the list of things I have recently replaced:
rotor, distributer cap, wires, plugs, coil and installed a clear fuel filter.
I have also rebuilt the carb.

The problem is never when car is cold only after it has been driven for some miles does it act up.

Thanks
Mike
