Is this at idle with the engine at operating temperature?
If so, your running to rich.

Couple of things to check:
- pilot jet: clogged? Sounds like it, and it's the smallest jet hence most likely to clog first.
- idle-screws still in their correct position? Mixture & slide screws I mean.
- if you haven't closed-up the small bore to the membrane-valve (LHS of carb, under 4 screws) it may be that this membrane is torn/broken or that some other fault here is to blame. Fix it by putting a small drop of epoxy-glue in the bore of the cover.
- the carb2rubber connection (on the head-side) is leaking. Go outside (duh!), start it up on choke, and with a gas-burner (OFF, no flame!) blow gas around this connection. If the rev's rise there's a leak somewhere here.
Oh, 1 other point..... there's enough gas is there??
