Hi all thanks for your inputs. Yes John there is a restriction on personal importation. Its the customes duty u have to pay and more than that its the headache one has to go thru if the customes guys stop your parcel at the dist center. A carby could maybe slip through but a full engine is out of question!
But i get the idea, try getting the tried and tested engines, and only if you absolutely cant, then go in for the sprayer.

.cheers....
