Just limped back home after breaking down 5 times on a 5 mile journey. Symptoms - lack of power, then engine dies. Wait a couple of minutes then it restarts, runs for a few hundred metres then repeats itself. Back home I've noticed the fuel pump (electric) becomes much noisier just before the power fails (it's attached by rubber bobbins so is usually fairly quiet). If you put your hand on it you feel it thumping away, the engine note changes (becomes irregular) then it'll revert to its normal state and the engine runs smoothly again. So I'm thinking it's definitely fuel related It's an elderly (6 years) JK pump so is this behaviour a sign of it beginning to fail or are there other areas I need to investigate before replacing it? Blocked fuel filter, dirt in the carbs? Fuel pump regulator failing? It's a type 4, twin Brazilian Solexes, the attached image shows the set up of the pump and regulator. Sorry it's a bit rubbish but it's pitch out there and not the best camera phone.
