Thank you for the replies. I will look at all the linkage again although I already looked at it once and don"t think that is it. I had not given much thought to the carburetor being the issue, but I will check it as well.
I didn"t think it was the carb because I increased the throttle a little and it didn"t go back down when I turned the throttle back. Being the bright guy I am, I did that several times and now it is stuck at a high rpm even though I can easily move the throttle handle.
Thanks again for the suggestions. I"ll let you know how it works out.
