Hi all, new member here who just bought his first cub this weekend. Its a 108.

The muffler is rusted out. Theres big holes in the side. Where can I get a replacement? And what other models use the exact same muffler (so I can expand my search for used mufflers).

How much blowby is normal? I read something about a negative vacuum crank pressure setup and I'm not familiar with that. Basically I have normal/not noticeable blow coming out of the crank breather. If I remove the dipstick there's more air coming out of the oil fill hole than the exhaust. Although typing this out I just remembered there's a big hole in my muffler so that maybe explains why not so much comes out of the pipe. I did disassemble the breather to make sure its clean and working. Its a k241 block (according to the sticker).

I'm sure the old k241 10hp is tired and its probably due for a rebuild, but it doesn't seem to burn any oil and fires right up, haven't even set the valves yet. Yup dummy me didn't realize the valves were behind the breather or I would have done it right away.
