Distributor gear installation

No, the dist gear goes 1/2 turn when it's on no1 compression, and when it's on no6 instead. The trouble might be your distributor. It turns out that not all distributors have the tang aligned with the rotor in the same way. The fact is, it simply does not matter. You can dump the gear in any old way, dump the dist right in after it, and then bring no1 up on compression (Stick your finger in the hole, feel for compression) Then stuff the no 1 wire in wherever the rotor points and it will run just fine if the dist tang is "one of those," you can diddle the gear if you must. I never bother.
