Craftsman ltx 1000 riding mower (917-272480) won't start? It turns over fine but won't start. I replaced the plug, and it has new fuel. It worked fine when I parked it last year. I did drain all the fuel when I parked it. Any ideas?

Remove your air filter spray a little carb cleaner in it . If it starts , then check out your carb for debri inside carb.

I agree and also would double check for a spark
