Our 2011 2750 Dixie with a 27hp Generac decided to lose a cylinder today at 775 hrs. I pulled the valve covers to see what the valves were doing (hoping it might be as simple as a rocker or valve spring problem). The dead cylinder has an exhaust valve that is staying partially open. It pushes in by hand and comes back up hitting something solid, but it is not returning all the way. Is this the symptom of a burnt valve or broken valve seat? The valve lacks about 1/8" from returning the the same position as the intake valve. The other cylinder's valves match when they are at TDC. Pressuring through the spark plug hole just pushes air straight out of the exhaust with the cylinder at TDC. I am hoping at worst it is just a new loaded cylinder head and gaskets.
Thanks in advance!
