Hi Peter, try putting the pawl assembly the other way, that is take out the centre screw and flip it over, if its on backwards it wont "throw out" when you pull the cord. While you're there check the friction washers are present and intact, they should be about 1-1.5mm thick. Also make sure the friction washers are clean and dry and not lubed up in any way. Check the cup is also clean and dry and give the inside a light rub with some emery paper.
