ok Dennis I do think I have it, but one more thing... When I look at the
distributor the order of the plug wires (starting in the upper left hand
corner where the notch is located) is NOT 1,4,3,2 going in a clockwise
rotation.  So... could my wires be that incorrect ?? (I think they are
currently set as 4,1,2,3).  The Van seemed to be running ok before and it
has been a year since my last tune up which I did myself, but before that we
had a service station do a tune up... Maybe this is why the valvle
adjustment seems so different from what it was???

What do you think??
