SOURCE: replacing front rotor
after removing the wheel &caliper depending on rust build up you may need to hit the rotor between the wheel studs this may take some time after removal check for rust build up on hub remove rust with hammer, sanding&scraping put some anti seize lube around hub making sure no rust is caught in between depending if you are replacing the pads you have to push the caliper piston back with a large pair of chanel lock pliers or suitable tool,then you can reassemble.thanx from schleck

* All brake rotors have a discard dimension cast into them. Replace any rotor that does not meet this Specification. After refinishing the rotor, replace any rotor that does not meet the minimum or discard thickness specifications.

Timing chain and gears may need replacing. Is the timing correct? Like number 1 at top of compression stroke and the dist. is on 1. How about a new coil too. Try a coil first. They go bad on these a lot.

Fouling occurs when the spark plugs' firing tip becomes coated with excessive fuel, oil, or combustion deposits so that it is unable to produce a spark. A plug can become fouled from continuous low speed driving, improper spark plug heat range (too cold), improper timing (over-retarded), too rich an air/fuel ratio or an oil leak into the combustion chamber. A variety of self-cleaning features are designed into most plugs to reduce fouling.
