i need some help.

My son has recently bought himself a Ford RS Turbo, 1986.. He has farted around with it without knowing what he's really doing and has messed up the timing.

Could any of you guys please tell him what the timing should be set at.

I appreciate any help that you could give. (he's driving me mad), as he wants to go and play with his toy.

Thank you
