Thanks for your answer.

When cold the pin is on top of the most left mark (rpm starts around 2000 )
After a minute or so it goes down to 1000 rpm and then to 750 rpm and it is there when the rough idle starts.

When engine is Hot temp the pin moves to almost to the maximun right mark but not totally. Engine works fine when is hot (no rough idle at all) .

I will take the van to the mechanic on saturday to see if he can adjust the cam adjustable screw more to the most left position (when cold) to see if there is any effect.

Keep you posted on results

Thanks a lot
