More carb troubles, engine won't return to idle revs
billdn:
Going to go for full strip down, re clean and reassemble. In meantime I'll recheck tappets and timing in case it's slipped but shouldn't be problem 😉
Oddjob:
Did you replace the o-rings in the manifolds Bill?
Scottish Badger:
Sesman, yes, fully stripped for ultrasonic cleaning and all ports blasted through with compressed air afterwards.

All new o rings everywhere in carb including manifold. 🤔 you can see why I'm confused , seem to have done everything right, obviously not but as to what it's a mystery!

Not sure if this is relevant but:-
When it does not return to idle revs does unscrewing the knurled main throttle screw adjuster reduce the idle to normal now or is it still as it was at the start of your post?
