Bynom was sold the dump by Tecumseh just before they went under.
This left them short so Stens ended up buying them out.
Stens exited Australia because they could not & would not try to understand the Australian market.
All Power took over the distribution of Stens in Australia and so became the Tecumseh distributor as well.
Go to an Allpower franchise and see how you go.
Allpower are of coures a Melbourne based company so AFL is the most important thing in the universe but eventually they might come good.
If nothing else some of the customer service staff are ex- Tecumseh.
And it would be reif you mentioned which one of the 75,000 different Tecumseh engines you are chasing parts for.
