I discovered my engine was running on 3 cylinders because there is no spark getting to #3
So.. I popped the top of the dizzy to have a look at the points. It seems that the points are not opening for one of the cylinders. The problem is that when I adjust the points to open for this lobe.... the points then don't close on the opposite lobe. I have spent ages trying to make an adjustment with no luck.... am I on the right track here?
