[diesel_mercedes] Re : '81 300sd running weird & smoking

 


Look at the clear plastic intake fuel screen right between the steel tube and the injection pump , left inner fender area ~ if there's any crud in that screen , remove it and blow it out backwards & re install , go buy two more of these and be _SURE_ to only accept the clear ones so you can -SEE- the dirty fuel before it clogs & causes poor running .

If there's lots of crud in there , I'd replace the spin on secondary filter too , fill it with Power Service DIESEL KLEEN before installing the new filter , Power Service products are found in truck stops , Auto Zone , O'Reilley's and other FLAPS .

Also , look at the firewall where the throttle linkage has a pivot , it was white plastic when hew but often crubles and allows the linkage to flop instead of only allowing rotation , if this is bad , make up a new part of cork or whatever and begin searching for a new one by price . when this bushing thing goes bad , it allows the linkage to liftbup instead of rotate and open the fuel in the injection pump .

Don't panic ! most of the time it's some simple thing or a loose screw etc.
