Welcome!

A few questions:

Where are you?

How do you know that it's running rich? Does it bog down? Does it run without the air filter? Is the air filter completely shagged? Are the plugs black and wet?

Do you have a manual?

Plugs should be DR8-ES: you can get them from David Silvers.

You can't change the leads as they are integral to the ignition coils. You can change the plug caps though.
