i looked up on anders somight to see what the numbers mean,
and one is listed for a 2.0 , 74-76 the other one(cleaner one) says 75-75. i can tell you the both ran like crap compared to whats in the car and i really thought when i bought the nice lean one with all new stuff inside it would run much better- one onther thing is they are off from each other 180' so no wonder one ran bad but the it doesnt explain the clean one on right- are they both for a d-jet or one for L- jer and does it matter?

Probably have different advance/retard curves, with the one for the 1975 being more retarded so the cars woudl pass the stricter emission requirements in 1975. |

I seem to remember the end letter (VW) A,B or what refers to the type of vacuum unit,have you checked the movement of the advance plates must be free and easy. These units have a bad rep for sticking up on the advance plate a very common issue ,seen lots when I rebuilt them years ago. |

I think I can see one of the mounting screws for the trigger points on the left side of the dirty one. I'm pretty sure I can see the end of the trigger points cover on the clean one.
That would say they are both D-jet distributors. --DD |

Might want to check the vacuum canisters to see if they hold vacuum. Then, check the advance movement, as mentioned above. |
