scoobybug

Hi havent posted on here in a while, if anyone remembers im the one with the scooby turbo lump in the beetle.
Got a problem with tick over that being it wont now! was all fine and running well but when i start up it runs for about 10sec then cuts out, havent done anything to engine recently so not sure why its just starting doing it??
Any thoughts or ideas would be much appreciated.

cheers scott.
