Last two vanagons I fixed, for this same thing, running weakly........
It was when I checked the fuel filter on each of them, that I found 'the
problem.' 
One was water in the fuel ( likely this time of year ) and rust in the fuel
filter, 
And the other one was a dying original fuel pump, and metal particles in the
fuel filter. 

Timing curve ? 
Throttle switch adjustment ?

Does it run fine once you're up to speed?  Possibly vacuum line to the
distributor. Did you check all vacuum hoses?

Anyone have a moment to share their opinion? We were supposed to go
camping this weekend but the westy's conspiring against us :(

Basically, there's no low-end power -- ex. if we're going 45mph in
4th and go to accelerate it just lags. Try 35mph in 4th and nothing.
It'll get there after a little, but this is just not right. Downshift
and it's better, but not great.

Details: 1983.5 Westy with a 1.9 engine, rebuilt 25k ago. New plugs/
cap/rotor/wires. Had bad throttle response and replaced the AFM with
a known-good unit. No gas smell. Idles fine.

Ideas? Tomorrow I'm going to start going through it -- any thoughts
appreciated!
