Wow frickin wheee Your cam destructed in a few pieces the piston rings are in there also and I think I see a piece of that in there.... The rod is in shambles. Maybe get a good tig welder, WAIT NO that won't do no good ..... LOL..
That rodent nest caused your problem from the get go........ The Command and the PRO are way better than the Courage............
If you can get a short block that matches yours for a cheap price then go for it... If your Command has the same size shaft then go for it.........
I have never seen a engine get tore up like that because of a mouse nest....... Usually you notice EXTRA heat coming from the muffler and actually feel the EXTRA heat on your legs or something......
Let us know how you gonna do the outcome Mon Ami ~!~!
