Hi Gadge and Norm,
Cheers for the information guys, I'll start prospecting for the parts! As for the starter key, it's not flat like the Indak kind; it is (was) a round red cylinder style with a small dome like push button (2 cm diameter) and a cylindrical plastic shaft (8-10mm) with a protruding solid 3mm knob on the end, so you have to twist it clockwise before you push it in to start. I think they termed it a safety key.
Most appreciated.
