Rough idle at start up fixed
 

My '83 300D was idling very rough at start up, mind you I am running B100 and Wvo. Obviously starting on B100 or so I thought. I was heading down to the cabin 2 days ago and lost all power.:eek: Filter plugged I thought, I was running on B100, but what had really happened was the Pollak valve was stuck open on the wvo side. So for the last 3 days I had been trouble shooting the gp system and all is fine. Running for 3 days locally on cold wvo was not a good thing for my MB, but the good thing to know is that it will start on straight wvo at 55f in the mornings of Western New York. So, I quess, I have a good GP system and good compression.:D
