Do use a stabilizer to prevent ethanol problems. We recommend Star-Tron or B& S stabilizer. Or better yet store your mower with a quart of canned fuel. Lasts a year, won’t clog up the carb. Drain the fuel. Run till it quits. Add a can of fuel and run for a few min. Will start when you get ready in the spring.
Change your air filter regularly and do not wash a paper filter or blow it out. Replace it.
Use original equipment belts. Fit alls do not fit mowers- they are too long, too short or not the right width, not the right V or not the right cording. Short belts put stress on the bearings and they fail sooner, longer belts result in a poor cut. See our tips about belts.
Electrical is getting more intricate. Don’t jump the mower off you car with the car running. Electrical is going to be more of an expense if you try to do it your self and don’t know what you are doing. You can blow expensive parts and make it more time consuming for the technician to track down all the problems.
