My original Cub Cadet has a 1971 K181 replacement engine that was running perfectly until yesterday. Just started to loose power then died. Sounded like compression issue before it died so I pulled the head off hoping to see something. Piston and cylinder look ok nothing major seen. I did observe something funny with the intake valve seem to open slightly after compression cycle. I don’t think this is correct and before I tear everything apart I was wondering if anyone has had issues with the valve springs in this engine or is there a common component failure that happens with this engine? Thanks in advance for any ideas.
