I have a Mercury 50 and an Evenrude 40, both engines have the same problem. When I pull the cord to start the engines the cord doesn't grip and the engines dont turn over, the cord goes back in no problem. I have striped down, oiled and put the pully system back together but it didn,t make a difference. <br />Can anyone tell me what the problem is as I don,t have a clue.<br /><br />Regards Rae.
