Hello!
I am also new here (6 years later than the OP).
I found this thread as I also was searching for the Air filter mount, as mine has identically split at the breather tube inlet.
Since I can't get a reasonably priced alternative, I am going to slather on some silastic.
Me:
I have a new (to me) 14" model 45, which going by the serial numbers on the plate and the engine, is likely a year-18months older than Andrew's.
Same 60102 motor (60102 0302 01 7005123) which I think means manufactured May 1970.
Scott Bonnar Serial# 45 18132
I bought it from a gent who had used it for the last approx 27years. And he'd bought it as a runner. So I suspect it has had close to 55 year's service!
I cut my lawn with it this morning before inspecting it further, all looks in great shape, only missing one reel adjuster nut, the handlebar plate, and it can breathe through the hole in the filter spacer. Motor starts second pull.
Will address the carby issues first, do another mow, then will tinker with it over winter.
