Where you need to make blanking plates, you would be better going with ally as it's going to be easier to cut and file if any finessing is required. 2-3mm will be plenty thick enough. I would bond some thin rubber to the clamping face to act as a gasket. on the exhaust, you generally use the exhaust to trap the blank off, so again something thin and rubber like. Even the proper Stihl kit just comes with an elongated triangle of rubber sheet 2mm ish thick for this purpose.
I'm not sure on the ms200, but on most stihls you could probably use a similar method to block the intake side with the carb and pressurise via the impulse nipple on the crankcase.
Yeah, I'm gonna use some tyre inner tube for the rubber, and kinda improvise.
With regard the exact composition of the plates, I'll be at the mercy of whatever the missus can got from the scrappy today. I said to her "steel" on the phone this morning, since I didn't seem prudent to baffle my lovely lady with too much technology. I mean she's doing me a favour driving out there... Well, we'll see...
(I do take your point, regarding ally, being easier to craft, though)
