I would remove that screw before you tighten it.  It should be very short.  Less than an 1/8' of threads.  Any more and it will run into the internals of the distributor and break stuff.  It may be why it was left loose.

Certainly, great point form Shvegel, sorry, should have thought about it...

I got the 66 230 and 71 280 engine that I’m setting up at the moment.
The correct fuel pump for it would be the one in post #10. Unit you have currently is the newer version pump later used in the likes of w107 and early 126.
Before changing anything I would still follow Sick advice to confirm that this is really your problem.

100% agree with Pawel.
Attend to that loose capacitator. The fact that you have noticed the engine stuttering when you move it around is a good observation. Hopefully with this sorted and the fuel pump attended to, you will have many years of hassle free driving !

The ignition condenser (the thing on the side of your distributor) has a function.  It limits the current across the points when they open. Running without it or even having it be intermittent can burn the points in very short order.  I would strongly suggest having the points replaced even if they are nearly new.

For anyone deeply into Kettering ignition systems I know my description is an oversimplification.  I just didn't want to lose the point behind a bunch of theory.

Update:
Thanks to all of your insights I think I'm on the way to solving my problems.  I'm changing out the condenser (MB original part - not off-brand) and points, changing all fuel filters, FOUND a rebuilt proper short-type fuel pump (thanks Bob Youngman).  Also thanks to Pierre Hedary who was kind enough to return my call and give advice.

FINAL REPORT

I finally got my car back with correct rebuilt short fuel pump (thanks Baron Youngman and Pierre Hedary), condenser, points, plugs, etc.  It runs like a demon!  Better than it's ever run! Thank you everyone for your insights and input.  Still a couple of months of top-down driving to enjoy.
