well i cleaned out the ISV & bought another WUR of ebay

attempted to start the car and it was so lumpy I thought the engine was going to come off its mounts, adjusted the mixture screw clockwise the revs picked up & it idles beautifully.

any idea why i needed to adjust the idle mixture after changing/cleaning those two items?

if i turn the idle screw clockwise am i enriching the mixture?

yeah clockwise raises the co mixture, either the old wur was making the car run too rich, or the new isv is allowing more air through it?

i may swap back to the old wur and see if i have turn the mixture back down, what i did notice is the car doesnt feel as lively now, theres a bit of raod near me & i struggled to hit the same top speed over the same distance, so somehow I seem to have lost the enrichment top end or the advance, I seemed to have cured one problem but created another ...........................

Hi
You are keen ! How many new washers will you have to use to reconnect the fuel pipes to the WUR ?
Have a look at the back of the old WUR and see if you can see the hole having been drilled to alter the fuel pressure.

what there where washers on the fuel lines  :shocked: :grin:

yeah checked that as soon as i got the old one off, to see if the WUR mod had been done it hadnt, I was going to put the old wur back on too see if i still had the original problem, I noticed something else today, i can hear a whistling noise from the replacement WUR sounds like its coming from the air hole on the front face of the wur , the one with the plastic cap on, is this supposed to make a noise?
