poor air fuel mixture

Often, it mean that the clutch stay engage.Now the question can be, is the idle to high for the clutch to disengage while at idle? you might try to reduce the idle speed by turning eather the nob on carburator or the ajustement on the cable.then if the idle is very low and the clutch still engage (that is why you can not shift) you migh want to check at the clutch and see if it is not stuck.

The problem would appear to either be with the mixture or with the head. Too rich a mixture (too much fuel) will cause black plugs - when you take them out do the engine and plugs smell of petrol? You need to adjust the carburettor. Mark where the throttle screw is to start with and then slowly screw it (in - I think) to reduce the petrol flow.
The other alternative is that their is a problem in the head. Does the engine blow a lot of blue/black smoke out when it is hot. If yes it means a full engine strip down!
