the L & H screws on the side of the carb are set to factory settings h =1.5 l=1.25
the engine seems to really struggle to move the car but then when its moving it really shifts i take it that this is a problem with the L screw which way does in need turning

ie leaning off or turning up ie more fuel ?

thanks


oh and second question last time i had the spark plug out i noticed a load of black on the top of the cylinder i asked some local bikers they said it was oxidization to remove this they said to use REDX ??

is this a good idea and does any one else have this black on the top of their cylinder will it do the engine harm and how can i prevent this in the future..


any help would be appreciated
