springs on throttle bodies

[johan123m]

I guess the returnsprings on my throttle bodies ('73 mfi) are worn.

the throttle plates don't return to a full stop so the micro switch isn't engaged and the car starts running way to rich

Is it an easy fix to change these springs? are they still available at porsche?

or is their another cause...i read in some treads the throttle valve bushings could be worn?

I don't want to spend to much on a rebuild of the throttle bodies because I'm building a new engine, so a temporary solution will work. Put an extra spring on the throttle linkage perhaps?
Thanks
Johan

Try WD-40 or penetrating oil on the springs/shafts before you get too worried. You'd be surprised how far a little lubrication can go on this old junk...

If you still have problems after a good spritzing, then try lubricating all the ball sockets with grease - DO NOT ADJUST ANYTHING!!!
