Hey guys, I'm new to the MB world. I know the terminology for modern fuel injection, but don't know squat about what words to use for my 84, so please bear with me.

Think about the top part of the engine, just under the air filter stuff; kinda like where a carb would be located.

This part will probably confuse people but here goes...

I broke off the top part of the bolt that holds the vacuum plate (my term) to the fuel inj. arm (my term). The vacuum plate appears to be aluminum about 5" in diameter and is attached to an arm that is attached back towards the round fuel injection distributor/head. The arm/plate combo gets sucked down once the engine is started. I think the downward movement of the arm causes fuel to be squirted into the cylinders.

Anyway, I broke the head off the bolt that holds the "vacuum plate" to the arm. Then I broke an extratror bit off in the bolt and now can't remove the extractor bit. (I got into this predicament because I have a high idle and was trying to understand how everything works, but man, if I had only know what I was getting into! But that's a different story.)

So, I'd like to know how to replace the arm (because I can't remove the extractor bit in order to reattach the vaccum plate).

Does any know how to replace the arm? Or have any suggestions about how to resolve my problem?

I've spent many hours searching this and other web sites for the removal procedure, but couldn't find anything.

Thanks for any help!
