Mick,
I have a victa jet in my workshop that I have not done up yet which might be of some help as an example. If you go to our main page you will see a link called contact us showing when we are open and where we are which is not that far from the north shore.
The 125cc victa engine is quite a good one and you don't have to re sleeve just have it rebored and replace the piston & rings. I should have all the parts you need in stock.
As to the industrial type victa engine I have not heard of that.
