If it winds then my money is on so called "dribbling" injectors, as k-jet injectors get old they wear at the nozzles slightly and allow the fuel to boil off and turn gaseous, it then takes a lot of winding to expell the fuel vapour from the injector pipes, and get liquid fuel back to them. Try a new set of injectors in it, they can be had off ebay. This is a common problem, injectors usually last about the 50k mile mark.
