Tips for storing and starting mower for the first time this year. Every fall, remove gas or add gas stableizer to the gas. Spring: change oil,replace sparkplug and fill with fresh gasoline. Starting: turn engine over by pulling rope or using electric start until it starts, but if it doesn't start in the first 3 minutes; make sure its getting gasoline (gas lines valves must be open). Try again and if it still doesn't start in another minute, you should take into servicing business.
