HI, my name is***** will be assisting you.So when you pull the trigger it actually slows down and when you release the trigger it speeds up, if I am understanding your issue correctly.I would look for an air leak between the carburetor and the cylinder(plastic isolator flange loose or cracked, bad gasket).Thank you it has been a pleasure to assist you.Please take a moment to rate your experience.

I haven't had a chance to try the suggestion yet. I had this problem one other time and a local authorized service center said that it was the mag. ??? They changed the mag and it didn't help. I have a lot of 2 cycle experience and my instincts tell me that it is an air leak. I was just hoping that it was something else cause I didn't want to dig that deep. You already charged me the balance so consider it done. I'll just have to get into it when I can.
