Dear Vanagon List,

Thanks for all your help.  Several of you suggested the Air Flow Meter.
I could see that someone had already had the top off.  I normally hate
to mess with these because I don't like to cause more problems than I
solve and I usually have a good used one sitting around for the Vanagon
to just pop on and see if that is an issue.  However for the 78 bus I
didn't have a good used one so I had to work with what I had.  The
tracks were worn at the low rpm range which is where he was having the
bucking.  You could see white in the tracks where the arm had worn
through.  I found this neat Youtube video that walks you through this
repair and it was simple.  You can check it out here

Now the bus is back on the road, running sweet and hopefully it should
stay that way for the rest of their journey.  The customer is a Jazz
Saxophonist who is touring the country with his wife.  A nice couple.
They wound up camping out here for four nights until I could finally get
this figured out for them.  Not my normal thing but this time of year
with folks traveling you do what you have to do to help get folks back
on the road.

Again thanks so much for the help guys, you are the greatest!
