Sorry in advance for another very basic one.

I can apparently do the job without a locking kit, but just a simple starting point:-

Do I set Nr 4 cylinder at tdc or on 10deg timing mark if I want everything to stay in one place?

Thanks.

If you're just changing the cambelt then it doesn't really matter where you set it as you can make up the various pulleys with tipex before taking the old one off. So long as it's all in the same position when the new one goes back on all should be OK.

Starting from scratch though or if you suspect the existing timing is out then you should set the piston to TDC.

Be careful to correctly line up the pulley for the auxiliary drive

I strongly reccommend to set all pulley markings, as it is really easy to move just one of four, espiecially when doing it for the first time.

I'd second that; the markings are there for a good reason so use them. It's true that you can set your own markings anywhere and as long as nothing moves you'll be fine but might as well use all the markings that are there for you. Number 4 cylinder should be at TDC and there's a mark on the crankshaft pulley for this. And don't forget to order a new set of knuckles for you as you're bound to loose some  Cry (or have lots of plasters handy   Grin ) I always scrape off quite a few of my knuckles when changing the belt on my Trevi  Cry Grin

There's no proper mark on the idler shaft pulley so make sure you add one. Be careful not to move it as it'll move the distributor and the ignition timing will be out. It's a good idea to always check and if necessary reset the ignition timing after changing the timing belt.
