So I have a G2160 just purchased. Runs like a champ fairly well cared for. Only thing bothering me is the HST pedal. If the engine is off (now after lubricating everything) it moves freely and returns to neutral just fine. But with engine running it becomes stiff and will only partially return if at all. Shut it down and it works quite well. Very puzzled by this. Any help appreciated. I did see an old post of similar nature and person said they added second return spring. I would like not to do that. I wonder if these G series machines have this as a common trait. As about a month before I bought the 2160 I looked at a G1860S and it did the exact same thing
