Should my Van have two marks or only 1 mark?  Usually you have 1 mark to represent TDC and a second to represent optimal timing.

Thanks!

    To set timing, do this:

    1.    unplug idle stabilizer connectors from idle stabilzer, and plug the connectors into each other;
    2.    use plug wire number one to drive your timing light; (passenger side, closest to headlight end of van)
    3.    timing is set when mark on pulley lines up with the line where the two case halves join - that is the other mark you use;
    4.    performance is often better when pulley mark is a bit to left of case mark.
    5.    When timing is set properly, reconnect idle stablizer connectors to idle stabilizer

    Hope this helps,

    I have a 1.9 L 1985 Vanagon Engine type DH.  I believe the Bentley shows timing should be 5 ATDC.  But this causes a few problems. 
     
    First the pulley does not have any timing marks that show 5 ATDC.  Only a single mark to show TDC.  I did notice the pulley does have some partial holes in the back of the pulley that might represent something.  I believe this is for a special electronic tool used by the VW dealers.

    Second, the engine runs really bad at 5 ATDC.  It seems to run best if the timing is BTDC.  In fact, the more I move the timing BTDC (Rotate distributor counterclockwise) the better the engine runs.  Eventually the distributor hits a side and can not rotate any further.  Also when I reconnect the Idle Stabilizer, I noticed the timing jumps all over the place.

    So, what am I doing wrong?  Any ideas?
     
     

    Take care,

    Paul
