Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

My 10 1/2 yr old mower has been getting progressively harder to start the last couple of years. To remedy this I have to squirt some instant start type freon product into the carb and then  it starts immediately.  Finally this past winter I had the shop replace the carb. It is still taking 8-10 pulls to start. That is after replacing the carb, plug, and air filter. Of course the fuel is fresh as well. Am I expecting too much from a 10 year old mower or is there something else I am neglecting to replace/adjust, etc?
