New to this forum, came across it while looking for parts for my old Retravision Contessa. Its a great mower, starts first pull every time.
I was chasing a throttle cable as the outside cable broke about 20mm from the carbie. After failing to find one i just remove the outer broken bit and shortened the other end. Good for another 20 years.
I inherited it from my father in about 1985. He had bought a new 4 stroke as the Contessa wouldn't start.
I cleaned the points and carbie and its still going, almost 40 years later. Its never been rebored and still goes well, though obviously a bit weaker now.
