Spark arrester??? Tricky questions, POWER VS.LIABILITY VS. WARRENTY.<br>Man I wouldn't get caught without a spark arrester in my machine. What happens if a spark flies out hits your gas can and catches your clients property, worse yet, your clients house on fire? This happened to a friend of my family. Was working with trimmer, spark was thrown, hit the clients gas tank in boat that was next to grass and driveway, caught fire burned up the boat and most of the client's garage down. Our friend lost everything (house, business) because he was sited by our fire department for using a machine without a spark arrester.<p>2 reasons for spark arresters to get clogged up on NEW machines, running too much oil with your gas and not running your machine at full throttle.<p>After they changed the type of gas that they sell in California 3 years ago, we had problems with all our machines. The gas would not burn hot enough; 2-cycle oil wouldn't burn all the way. Fowl everything, spark plugs, and muffler, spark arresters ECT.. The solution: Run machines at full throttle, change spark plugs more often, clean muffler and spark arrester of carbon and oil deposits.<br>Jean<p>----------<br>J-LC Landscaping & Maintenance Gardening<br>C-27 Ca Contr# 770044
