I guess the unknown is: am I going to keep stripping cylinder studs - or did the on-off-retorque of the head lead to a failed stud - which lead to the other issues. I think Craig probably has the cause of the broken gasket identified.
Considering if I will run a dozen heat cycles and see if it now holds up - or if I should take the plunge and replace the cylinder.
Then of course- I would have a whole different set of issues - like - do I go nicasiln and get one of those fancy BGM pistons or the like. I do like their shape...
Ginch - I have an iPhone with Safari as my browser - and it just shows up like that. Don't think I am doing anything out of the ordinary. Perhaps its the browser?
Voodoo - ha! indeed. I must be living well - cause that bolt could have thrashed pretty much everything - and I got away with a gas rinse of some thinly "bacon sliced" chards and not much worse. Damn lucky really. I'll make sure to say two Hail Marys and light a candle when I visit the Vespa museum in the future.
Hope to strip down chassis or paint this weekend.
Pull motor - and examine internal frame for any signs of stress after my short but somewhat aggressive initial tests.
