Als je de gereedschapjes hebt om naald (en sproeier) af te stellen zou ik dat zeker proberen. Op kjet.org staat het carburateur-handboek, TP11740-2, met alle waardes, hoogtes etc.
In het B20A boek (zelfde carb) staat een dwarsdoorsnee bij stationair, ik zou zeggen dat de luchtschuif met naald zeker een mm opgetild is. Volvo tekeningetjes zijn vrij realistisch is mijn ervaring.
Hier nog een stukje oude school afstellen (uit: http://web.archive.org/web/2002091115593...rbsIII.htm)
Mixture Adjustment: The mixture is tested by inserting a long thin screwdriver into the air intake and lifting the air valve as shown in the adjacent photo. The air valve should be lifted approximately 1/4 inch. If the mixture is correct the engine speed should be steady or increase slightly at near the 1/4 inch lift point. If the valve is lifted further, the engine should slow down and possibly stall. If the mixture is too rich, the engine speed will increase maybe 10% or more, and may not tend to slow down till the air valve is lifted much more than 1/4 inch, depending on the richness of the mixture. If the mixture is too lean, the engine speed will decrease and possibly stall. Before each test the throttle should be opened increasing the engine speed to about 2000 RPM for a few seconds to clear all fuel from cabs and manifold.
