Thanks Grumpy,
The manual and parts list will be very useful! I was hoping for more of a 'replace the carb to tank gasket' type of response, as the leakage seems to be the only thing that has changed since the haphazard rebuild. Although pouring random quantities of fuel down her throat to start her up is obviously not a very professional method, it HAS always worked very well in the past, hence my question.
Considering that Betty is (has always been) held together with bits of twisted wire, shoelaces and badly painted rust I figure any minor improvements and/or replacements that can be suggested by the experts on the forum here will be far better than the alternative (wife says take to tip, buy new mower). Although a rebore, valve job and forced induction are probably not on the cards anything that will return her to her former glory will be considered rather than consigning her to the scrap heap.
I have compression and I have spark, which leaves fuel. Maybe I'll just throw on a new gasket and try some fuel that ISN'T mixed with 2 stroke oil and is thirty years old and see if she wakes up again.
