Re: Lawn Boy 10547 hard to start/smokes
First off Welcome to MTF! In regards to the problem you are having, it could be a problem with the coil, do you have any way to check for spark when you are first trying to start it? Also these mowers are prone to leak fuel through the carburetor while the machine is not in use, therefore flooding the motor with unburned fuel, leading to hard starts and excessive smoke. This can easily be remedied by installing a fuel cut off switch and better yet a fuel switch along with a fuel filter. Turn the fuel off after each use and you should be all set. Search around this site and you will see plenty of examples of this. I'm sure others will chime in as well. Good luck with the mower, that is a very nice machine!
