Check your timing... it sounds like it's too advanced. As far as I know, you tilt your rotor to change it (using a timing light to measure off the timing belt) or just use premium gasoline (the rumor is that it detonates slower).
Your engine knocks when you cold start it because the motor oil is not viscous enough to lubricate crank bearings, cylinders, etc. warm it up first, engine will last alot longer
