/diy/ - Do It Yourself

Have a scooter, 50cc 2stroke. Uses quite a bit of oil, smokes on startup and sometimes I've got to spray some easy-start in the carb to get it running if it's sat overnight. The starting issue may be dirty jets as I ran it out of petrol a while ago, cleaned the jets but might not have done a proper job. What do ya reckon's wrong with it?
