REVS take ages to subisde

Standard ET3, clean carb, standard jetting, fuel pipe sensibly routed. Takes ages for revs to drop and I mean a good deal of time. Engine starts and runs great except for this problem. Its probably simple but its got me stumped.

Manifold n carb are nice n secure also.

PS. my tuned ET3 goes like a bitch now after a D36 needle and 266 atomiser went in (cheers to readspeed for the advice)

Alright,

I had exactly the same problem till I sorted the mixture screw out. Give it a few twist and turns either way and it could solve your problem. I tried allsorts before I even bothered looking at it.
Nice n easy!

Though if I am wrong I apologise profusely.
