Starkpatch? Starkvegas? I thinks it's an hour and a half, maybe two. I
was briefly incarcerated at Moo U when I thought I wanted to be an
electrical engineer, before the differential equations and higher
levels of calculus convinced me of the error of my ways.

I may have lost my little S shaped piece of tubing that goes from the
crankcase ventilator to the air hose between the air filter and the
carb. Is that for emissions purposes or to preheat the air so icing
isn't a problem? Both seems likely. Can i live without it or must I
fashion a replacement?

Clean cooling fins, remove heads and clean carbon (if any), be careful
so as not to damage head gasket, find some sort of aluminum spray
paint and spray the gasket with it a few coats. Wiretie the various
wires neatly, clean up the oil spray that seems to be everywhere...

When it comes time to put this into the Royale, the Power Drawer is
already in it, but empty. Is it easier to take my Onan out of its
drawer and put it into the Royale's drawer, or should I take out the
empty Royale drawer and just slide the Onan drawer and all into the
spot? It would seem to me to involve less fiddly bits to be
disconnected and reconnected.

Clean it up, make sure nothing;s busted, Ty-rap <tm> the various wires up nice and neat. Carb ice is why airplanes have carb heaters. You see a substantial drop in temperature across the venturi, upwards of 40 degrees in some circumstances. With the air filter and bafflinfg back obn it's lessof a problem. And some Onans have the 'Winter/Summer" setting which moves a baffle to pick up intake air from the cooling stream where it's been warmed. Buttoned up and reinstalled in th coach it shouldn't be a problem. How far are you guys from Starkburg?
