Hello LawnKing,
I can't believe all the sudden Scott Bonnar interest in South Australia, it's incredible.
The machine you have is the Model 33 and the later variant as it was manufactured along side the model 45 in its early days of production. Your machine was actually built in 1971.
As far as the Kirby engine is concerned the starters are rather easy to change the rope in but it really is one of those jobs you need to experience yourself from pulling it apart as it's rather hard to explain.
The Kirby engine itself is a good engine, but their carburettors are rather finicky with the wear on the butterfly shaft being the major culprit. There are basically no parts available for these carburettors which certainly makes life difficult.
The best advice I can give you is to get it going engine and transmission wise reliably and once satisfied then I'd strip it to get the end result you want. No point in doing all the work and then find major issues that can't be resolved economically.
Cheers,
BB.
