Unfortunately for you that kit looks like a waste of money, it will probably be worse than using an original distributor and standard plugs. They don't list different advance curves for different engines so it will be another "lucky dip" distributor.
That aside I don't think it will actually be the issue you are having currently. Still, Please check the timing throughout the rpm range first before adjusting the mixture.
Distributor or dissy cap? All timed in correctly?
I doubt it can even be timed correctly with that distributor
