I have a 21" Honda push mower with a pull start as well as an electric start. I was cutting a customer's yard and killed it to empty the bag. Went back to start it and the electric start just made a whizzing noise. It seems to me like it might be the starter. It starts, though, by using the pull rope. I think it is a HRX 216...not sure...haven't went outside to confirm this....just going off the top of my head. Can anyone diagnose the problem? Called the dealer and he said that it could be a number of problems and I should bring it in.
