Ok there are only a couple of things that an engine needs to run,

Fuel
Air
Compression
Spark
all that the right time.

So the first thing you need is to solve the weak spark problem. Without a good spark you will have a poor running engine if it runs at all.

I know that you have received another distributor but that does not mean it is a good one.

One of the guys in our club bought the "Zipper" from FSI. Although the spark was good, to get the engine to run well he had to throw away the instructions and play with the cam setting. Moving it a little at a time in each direction until it would run well. I'm sorry but I don't remember in which direction he had to move it, advance or retard.

What does the resistance read from the distributor body to the battery ground? Maybe corrosion in the head?
