Ok here is what i observed on mine: With the offset pinned dog aligned precisely pointing at the two roundish square indentations carefully turn over the distributor and then looking down at the shutter, the edge of an opening on the shutter should be aligned exactly with the center point of the hall sensor. Of course there are two edges to the opening, it will be the edge towards the clockwise direction. Expressed another way, look at the shutter with the distributer held plug to the top and the hall to the bottom it will be the left edge of the opening. Put a pencil mark on the shutter top in line with opening edge to judge where it is as the edge goes out of site when it goes into the hall sensor slot.

Hope you can understand my description and that this works for you.

BTW my distributor has the number 030 on it. Hope yours is the same.

What was the original problem? No start, no spark, no fuel?

Good luck!
