Ok I now have another victa that I have obtained, its not that old, but still has the black carby.
I can start the engine and after about a minute the motor will cut out, kinda like a fuel cut out. I replaced the black plastic carby with a known working carby and still the same problem, which has got me thinking that its not the carby that is the problem. So I ask anyone out there, if they know what else it could be? PS I think its a 125CC motor
Cheers
