Repairing a Super Tigre 75

I have an Italian ST 75 that I just love and it got clobbered the
other day. The carb and muffler were basically destroyed but the
crankcase and all the internals escaped miraculously. I know I can't
get Italian parts and I was wondering what I could expect by buying a
new carb and muffler set up and using them on the Italian crankcase.
Are the Chinese parts compatible with the Italian stuff? I hate to
give up this engine as its performed so perfectly for me.
