It's weak! Set it slightly richer. Also make sure there is a spring inside the carb (on the piston) - and some 3 in 1 oil in the dashpot.

Run the mixture nut downwards slightly - you could try 20w50 in the dashpot if all else fails.

It's exactly the same - nut underneath on the jet assembly - above the choke connection!
Page BBB2 of the manual - he is using a fancy SU spanner - but fingers will do!
