Hi all. I'm stumped. My usually reliable car is letting me down. I thought it had bad fuel in, so drained and put in good fuel. Cranked the new fuel through and it started but then cut out again. Tried next day and she flashed up straight away but died after 30 secs. Tried to wind it over but nothing. Came out next day and it's the same. It seems quite lumpy when it is running. Spark is good. Stripped 1 carb down so far and it's clean. Anyone any ideas??? Cheers all.
