Re: It Ain't the Spark Plug !
Oh, . . . sorry about that yeah, the muffler, 3-4 mo. in use was the problem., previous thread prior to yours, it was fouled up some how I'm getting another!
Here is a copy of the previous answer;
If you take off the muffler, to see if it is fouled, and start it up and forget that the idler screw is all the way in from the trial runs previous, make sure you have a kill switch !!
