I need a throttle bodie gasket plus two gaskets for the balance bar, is it possible to buy some gasket paper and make my own?

just use gasket glue

That lot is all under £10s worth anyway I think!

Ok, I have removed the balance bar and and squirted some gasket sealant over the o rings and around the surface, re fitted the balance bar and can still hear a slight hiss. On the passenger side there is a wire holding bracket which gets screwed down with the bar, this gives it an uneven surface, should I remove this bracket and retry sealing it?

There should not be agasket on the balance bar, that is what the 'O' rings are for, to seal it. The bracket in question should be on top of the balance bar, not underneath it, or am I misunderstanding your thread.

You are not misunderstanding the thread, the bracket was underneath before I took it off, that is probably why it had uneven idling, I will take it back off and redo it.

 

Thank you for the advice, much appreciated.

Yep the bracket must sit above the balance bar, make sure that the O rings are in good condition.

Cheers, I dont know if they are in good nick or not, but I have put some gasket sealant around it to, just been outside now, repairing it, I can still hear a slight hiss, but I dont think its comming from the balance bar, it sounds like its comming from the pipes at the back of the engine, I have got the revs at a steady just under 1000rpm at idle now. Is it normal for the revs to drop when putting your foot down slightly when the car is cold?
