I'll give you some more information its a 1.1 carb engine and i've bought it for this reason thinking it might be easy fix because I want to rs turbo it, but before I start the conversion I want it running right first, also the guy I bought it off is a gardener so I'm wondering if he's filling it with Jerry cans of fuel since he probably get fuel cheap off someone which will be crap fuel anyways, I might start with a full fresh tank of fuel from asda petrol station and run a fuel additive system through it, see if that's clears anything.
