Buy cheap parts and save!
Bought some cheap points from SimonBBS on Ebay and put them in my car about 500 miles ago.
Car dies. In the bus lane on the freeway. In the cold.
Towed home.
Long and complicated saga getting it going but eventually noticed this:
The moving electrode is loose in the spring, so even though the point gap is perfect, the points don't open !You can't see this in the car...
Lesson; buy brand name parts.
