CEN, I have a question. I called the U.K. distributor today about trying to get the NT18 engine sent to my LHS. They had no idea what I was talking about even though I gave them the part number. Is this engine not available in the U.K.? Also I was going to buy a new piston, sleeve and crank shaft for the NT16 as I have the older one (1hp) and wanted to upgrade the internals to get the improved power outputs (1.2hp). However if the U.K. is not getting supplied with new parts, I will simply be replacing the old internals with the same thing if you see what I mean. When will we be getting the newer parts over here? Please reply.
