oil pressure

the first time when it smoke bad i pulled plug and plugs were wet with oil. so i replace valve stem seals i fired it up yesterday and at idle it quit. put when you snap the throttle it would smoke then when it got hot it would do worse. i pulled the plugs again and they were dry. when i changed carbs it ran real rich till i had somebody with carb experince tuned. im starting to think like you guys said it not broke in all the way. the next question is how do i put a load on it to break it in. im new at this stuff
