Thank you all for your advice. I am now considering a new cam as well. 
What will be the best choice? I prefer better torque at lower rpm over power at high rpm. What will be the best choice for my engine? Swiftune SW5-07, Kent 266, Minispares EVOLUTION02? And what coil is best for my upgrades? I have 12V electricity (mini 1000 from 1974).
