Mower help!!

[webstertroy]

I picked up a mower a John Deere la145 for free this past weekend... Got it home changed the fuel filter oil plugs new fuel in it and tried to start it.. Well if I sprayed cleaning in it it started and woudl run only if I sprayed it in.. After letting it turn off I could not get it to fire back up.. I tested the coils one side had a little spark other side didnt.. I have ordered new coils today to put on tomorrow when they come in.. They mower had been sitting for 3 years.. I is a 2011 with 22hp briggs on it.. Any help would be great!! Also I put a new battery on it and it killes the battery with in 3 cranks.. Took battery back and had it tested and says its just fine any ideas?

Stop look and listen.
Slip the rocker cover off and turn he engine over by hand, watch the opperation of the vlaves then pull the plugs out and onfirm this against the movement of the piston.
remove the carb and clean it thoroughly.
When you ave reassenbled it blow air through the ventury and check to see t is atomising fuel, Do this outside & don't smoke.
If it looks like it is working then reinstall. if not back to the cleaning.
