Ah,the good old VV carb
Must be 20 yrs since I worked on one of those!
Exploded view here
A Top cover
B Manual choke unit
C Lever housing
D Choke cable bracket
E Automatic choke unit
F Bi-metal housing
G Air control vacuum
diaphragm housing
H Air control diaphragm
J Accelerator pump
diaphragm
K Accelerator pump cover L Throttle linkage
M Mixture adjustment screw N Anti-run-on valve solenoid P Idle speed adjustment
screw
Q Fuel needle valve
R Float bracket
From vague memory should be anti clockwise to lean mixture.
Check the choke isn't stuck on, and check the throttle diagphragm.
If you take off the airfilter, the variable part of the venturi (hence VV) should have resistance on it when you slide it back, if not the rubber diagphragm can be split or gone all 'sticky'
Also worth checking the accelerator pump diagphragm is not split as well.
Parts from here..
