I just stumbled upon the “donneysaab” channel – apparently Tom Donney of Tom Donney Motors – on Youtube. The channel has a few quite interesting Saab videos. Check these out:
Saab two stroke head milling. How to properly relieve the Saab two stroke head for over sized pistons or to restore the correct “crush area” in the combustion chamber.
And a pretty sweet looking 93 GT750 undergoing restoration.
There’s more tips and vids on the Tom Donney Motors website.
