It lopes, the engine light flickers as it lopes. Once I get going it smooths out and runs well. Just replaced all the spark plugs. All were picture perfect.

Good evening.

It sounds like the idle circuit of the carburetor is not working correctly.

Did you try adjusting the carburetor idle air screws?

Can you upload a picture of the carburetor with the air filter removed?

I will try to get the picture to you. Last night after getting home I took a video with I hope good enough to sound. I do not know if I can upload that, as I said, if it is good enough. Rats! It is not letting me access the video file. I will have to do it again tonight, and add per this site's parameters.
