I have taken off the air filter box and ran it that way
taking the turbo inlet tube off was to prove the flapper in the box below the air box was working

Yesterday I took off the speed sensor that reads off the flex plate (starter ring gear)
It had some filings on it but looked fine so I wiped it off and reinstalled

and to make sure it was actually working with the engine running I un-plugged it from the connection up where it is secured to the intake

The engine stopped when unplugged so it's working

A couple of days ago I (with the advise of ROY) I had the intake off (again I'm getting good at it)
so I took out the fuel shut off switch and ran it with no effect

We did this because the stop lever was kinda bobbing a bit while running
Thought maybe it was pulling vac. and kinda "retarding" fuel delivery...... had no effect

I'm going out now to try the WD-40 thing....
No change in RPM

I am unable to just throw parts (more parts) at it like injection pump unless it actually needs it
I had a spinal fusion and I am still not back to work (well they laid me off for some reason after I got hurt) so funds are more than low but I still need to fix it without taking it somewhere

I am at the end of my rope thanks for all your help
I still think with Roy's help and many others of you out there I (we) can figure it out
Because the benz owner community and this forum are the best!
