Hello to everyone im new to this forum, i have a cub cadet 108, early 70's. i think a 72. last winter i was plowing my drive when i heard a loud pop and the engine quit. it didnt restart and i havent looked at it since. im not very mechanical and was wondering if anyone had a clue what i broke inside the engine. i was gonna start to rip it apart myself, but like i said im not so mechanical. thanks in advance.

Welcome to MLMF, Mark!
I think the first thing to check is if the engine still turns over (by hand) freely. If it does, It could be something as simple as a stuck valve. If it doesn't it might be more serious like a broken connecting rod or stuck piston.
If you're not mechanical now....you will be
! It's a simple matter of removing each part and laying it out in order, on a clean table top or work bench surface. If you have a camera -Take pictures as you go and eventually you'll find what broke. Once you do find it, there will be lots of help and opinions on how to proceed. Often, it's a simple matter of remove and replace (with a little machining in between). Others times it may prove to be a catastrophic failure where replacing the entire engine is more economically sound then repairing the old one....Regardless, You'll be doing what you would have to pay someone else to do anyway.
Good luck and keep us informed will ya?

Greetings, Mark. As Mark777 said, this will be a great learning experience. A machine of that vintage is probably well worth repairing and getting back into service. There will be plenty of people here to offer advice and moral support. Good luck!

Hi Mark416. I just sort of knew lefty loosey, righty tighty when I started working on my stuff, so don't sweat it. Like the other guys said, take your time, take some pictures, take notes, and enjoy it. And don't hesitate to ask questions as you go. Those old Cubs are worth the effort.

Welcome Mark!
No matter how long you wait it is not likely going to fix itself. Been there tried that myself.
If you go to www.kohlerengines.com you can download and owners and service manual . Look under K241 K series
