hi all, my first time here so please bear with me... I have the offer of a beautiful K plate Sovereign, which appears to start but wont run after an initial 'burst' of fuel has been primed - I know this sounds like carbs but it aint! Is it likely to be a dodgy fuel pump or someting more sinister? If its a pump, can anyone recommend a good supplier? I have found justjags on the web who look OK...
