camshaft

I have a Cub Cadet Pro Z 154S with a Kohler Confidant EZT750-3011 (747cc, 27HP, EFI) engine. I believe the previous owner neglected it. At 385 hours, I found that the cooling fins were almost completely blocked. I cleaned them out, adjusted the valves, and did the typical year-end maintenance...

Ran into an interesting one. Briggs Twin Intek 23HP broke something while mowing. Tore it apart and found the camshaft broken into pieces and an exhaust pushrod mangled up inside. I can’t for the life of me figure out how that pushrod got into the crankcase? All 4 tappets were I place. I can’t...
