[urq] suddenly lean again and some measurements

[Ado Sigal]

It seems that enrichment circuit isn't operating properly, and it sounds 
like el.contact problem. The t/switsh operates solenoid (it clicks when 
the switch is on), and the solenoid routs the m/pressure on WUR, which 
changes the secondary FP and gives more fuel. So check el. connections 
for corrosion, t/switch function and adjustment, the wiring and the 
solenoid, well and the piping while you in there.

May Audi Gods be gentle with you and the rest of us this year,

Ado

When I lift off , change up and re-apply the accellerator the power has gone and the mixture has gone lean. If I were to keep my foot down this condition would remain. If I lift off and then reapply the accellerator then the power returns, the mixture returns to rich and it would  continue to pull until I ran out of revs. If I keep my foot down instead of changing up the mixture remains rich so it does not appear to be a case of fuel starvation.
