Dear group, I have posted several times about the engine being sluggish on takeoff in my M-10 and the mechanic found a stuck intake valve on the number 4 cylinder which could not be fixed so I am having the cylinder replaced. What would cause this to happen? The oil was changed in January and it has only been flown around 25 hours since the change. My mechanic I am using now did not do the annual and the other cylinders where not damaged. He is not sure why this exhaust intake valve stuck open, and the others appear to be in good shape after breaking down the engine.
Also the cylinder head temperature gauge was reading around 400 F which. I landed several I think was because of the stuck exhaust valve on number 4. Has anyone else had this experience and what was the outcome? Alan
