Thanks for your reply, the issue is i'm at 8 half turns on every screw or very close too - i.e: open them much more and they'll fall out !!!

CMA also says if you have to get past 8 half turns without increasing idle then the holes are carboned up and need to be cleaned but i can assure you they are as clean as a whistle.

The needles on the screws are also spotless and like knew shiny gold zinc since i had them re zinc plated when re building.

I also tried leaning up the mixture (in an attempt to increase the idle speed) but didn't seem to make a lot of (any) difference - have returned idle mixture screw to read spec (bang on 2.5% Euro) after the enrichment thermostat warms up which is definitely working since runs richer unit that kicks in, as it should.

Maybe i should lean it some more ??? Thing is with the hand throttle slightly up i can make it sit bang on 900 RPM and it will just sit there purring away nicely.

Maybe my accelerator / hand throttle linkage is out but for idle the throttle bodies should be sitting on the stops ?? and if i was to adjust the throttle cable to increase RPM that won't be the case... perhaps i need to nudge up the throttle butterfly stops so it rests, at idle in a slightly more open position ?

Its literally the last piece of the puzzle as the car is now running a treat. Nice brown furry plugs .........just cant idle

Driving me INSANE .....
