If you want it tuning when you get rid of the fuel smell take it down to Tony at ART down towards brasserie 99 at the B+Q roundabout, thats where I'm taking mine again when the respray is done. He's a top guy and made mine go like a missile!! I did a standing 1/4 in 15.2 in my standardish mk2 16v he rolling road tunes it for around £50.
I had a really bad fuel smell on the gf's polo and it turned out to be the fuel cap which had gone might be worth checking. On K-jet if you get a fuel leak it will not run as the system works on pressure so you would know about it!
If your stuck give me a shout a friend of mine has just broken a mk2 k jet 8v so have plenty of bits and pieces knocking around
