Any help will be good. :)

I'm assuming its an SU style carb?
If so, easiest way would be to get different needles for your jet.

These are a very poor carby setup. however try remove the emission gear, give the carbys a real good clean and make sure the chokes aren't seized. Also get a can of that subaru manifold cleaner and follow the process on the can I have found that effective on old carby cars especially if a elderly person has nursed it around most of its life.
