Answer
Hello Mark:

These Adjustments Depend on the the Make and Model of the Engine. Send me the Model and Type or Spec Numbers Off the Engine or the Unit Model Numbers, Please. With these I can Locate the Proper Manuals and Better Assist you. The Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. Thanks.
