I seem to recall that the intermediate idler is not connected to anything, it just is apart of the belt assembly. If correct, why the importance of the 4 o'clock position of that idler? So far I havent' been able to find the alignment marks for that position. Are they hard to find?
I am having to advance the dist. alot just to get the car to run correct. About 5-8 degrees advanced. It runs very poorly at stock timing. The smog guy thought the basic timing was out 1 tooth. In looking at it, the cam and crank seem to be on the mark. The intermediate I can't tell w/o taking off the timing cover.

The idler or dummy shaft drives the distributor and the oil pump.
The timing mark is a small dimple on the gear, the same as the mark on the cam and crank gears, the timing belt has 3 sets of white lines that will corespond with the alignment marks when installed correctly.
If the cam & crank are aligned correctly the car will run even if the idler shaft is not aligned, but you will need to adjust the distributor for ignition timing, if you are out more that one tooth you may have to remove the distributor and reposition it to gain the advance required.

The it seems to me that with basic timing OK, the one tooth that the intermediate sprocket is out is "corrected" with the dist. and then it is OK until I get smoged again and the car runs real ruff, but passes. The milage is OK, the car runs OK so I think I will just leave it.
