OK, took Jonathan's advice and actually managed to find a shop that sold the Gates kit, so gave the engine number and got the right kit - 01, except that the spacer in this kit was the correct size:)
Cleaned away all the mess of grated cambelt and carefully fitted the new one. What a difference! when I turned the adjuster anti-clockwise to take up the slack, and then to slightly adjust the timing, the movement was so positive - just a slight turn moved the timing marks quite a long way - nothing like the kits from before! Also, I struggled to hold the 30mm spanner at the same time a torquing the bolts, but no problem this time - in fact, I could set the final torque without even using the spanner on the rollers or the tensioners.
I did quite a lot of turns of the crank and the timing did not move at all after the initial adjustment. The tensioner did move and I stoped after each couple of turns and reset it, but the amount it moved each time after that was kind of random - however it never moved very far, so left it in the end.
Put everything back carefully, had a cup of tea and then started. Engine sounds beautiful. It's the first time that everything has been working right since I started as I also removed then head and changed the exhaust manifiold gasket, DIS pack and thermostat.
Drives very smoothly. Only thing I get know is that at at exactly 70mph I start to get a sound like a mouse with tin boots walking randomly underneath the facial near the bulk head. I noticed that the sound also happend below 70 and more pronounced when the heater is on - I turned it off because the aircon was drained for the head work.
Anyhow, will have a look at this tomorrow. Hopefully can start on the suspension work in a couple of weeks

Thanks for all your help folks.
