Norman,

Can you not weaken the mixture enough by screwing in the mixture screw ?

If you have a “Colourtune Plug” you can quickly check and see the imediate effect of any adjustments although the plugs are the best long-term indicator of  a good fuel/air mix.  If you don’t have such a magic plug, I would suggest tightening the mixture screw no more than a quarter turn at a time and then running for a while before checking the plug colours.  And you will probably have to adjust the idling to maintain optimum tickover as the mixture is altered.
