My mower's code is 92508 5157 01 85102505, so I'm tipping that the engine was manufactured in 1985.

It has a Vacu-jet carby which I don't have much experience with. Once I get the carby/fuel tank off the mower I should be right but I've had problems with the governor/throttle linkages. Is the process for taking the Vacu-jet off the same as for the Pulsa-jets?
