Now put in fresh gas remember nothing over 30 days old and use a 87 or higher octane. If it is a little hard to start you may have old gas in the fuel line and carburetor. Take your air filter out and spray in a shot of either or WD40 will work. Try and restart and you are ready to mow. Now is the time of year to walk around your house and check all of your windows and screens for needed repairs.
Warm weather is just around the corner and so are bugs.
While the weather is still cool it is time to get your screens repaired. This is the perfect time of year to take them in the basement or on a sunny day take them to the garage and repair them. If your not handy take them to your local family owned Hardware Store, and have them repair them. Don't wait till warm weather, when everyone else does and you have to wait weeks to get them back. If you have aluminum storm window and screens check the corners and latches.
