Good morning everyone,

A couple of months ago I wrote about my diesel's loss of power - finally
my shade tree mechanic did something about it - he says he's 'tuned' the
fuel injection pump.

Power is greatly improved, but under moderate to heavy acceleration the
van smokes a lot (black smoke). Oil, oil filter and air filter are
clean. A steady 60 mph gives no visible smoke. I don't really want to go
back to the mechanic for what I hope is a simple correction.

I know there must be a screw adjuster on the pump which sets the
injection quantity. I'd like to turn it back a little. Trouble is, I
don't know which screw it is. My (Swiss) Transporter manual (a bit like
a Haynes) only mentions how to set the idle and highest speed, but
doesn't mention this quantity screw, possibly for environmental reasons.

Can anyone help?

Regards from Holland
