OK Stevo, there are a couple of visual differences, but I can't remember off the top of my head!

I'll see if I can dig out the MC16/18 manual tonight and get back to you. If I remember correctly, the most identifiable features are the heads. Also, if the inlet manifold is on, then the MC16 rubber "boots" for the carbs are substantially smaller than the MC18 32mm items (26 or 28mm I think).

I'll let you know later.

Andy.
