Small Engines (Lawn Mowers, etc.): Craftman lawn mower 6.5, craftsman lawn mower, time joe

Question
have a Sears 6.75 craftsman lawn mower. It is very difficult to start. I had it serviced with all parts replaced last year and last week after I put in fresh gas again it has yet to start. What should I do. Any idea why this machine just wont hunt. This is like the third time and the machine has not seen tha much service since it was bought.
Thank you for your time.

make sure the parts you installed are the correct ones and that they are good. I have seen many parts (plugs) come in and were bad.Sounds Like the carb may need a good cleaning,do you use the primer bulb to start it see how many times it takes to start.

Thanks
