My YT3600 seems to shake excessively when running. This machine is new to me so I don't know if it is normal or not. I went so far as to remove the engine and open it up, expecting to find a counter balance shaft that was not timed properly but everything looks good. The shake is there anytime it is running, it does not have to be driving. Any ideas? Is there a common problem here somewhere?
Any advice would be appreciated. Thanks in advance!
