Craftsman tractor engine compression or timing issue
I have the same issue on craftsman with Kohler CV491S - 27501 engine. A coworker gave it to me and just trying to get it running. Won’t turn with spark plug in on compression stroke but take spark plug out and it will turn with less resistance. Flywheel key looks okay so I’m thinking it’s the camshaft and acr. Can anyone confirm it? Is there anyway to know for sure that’s what it is? I don’t have much backstory on mower other than it quit running so he put it in garage and left it for 8 years. His loss is my gain if I can get it running for cheap.
Questa è una buona domanda?

Hi @ltuck ,
I've moved your question to a new question on ifixit as it may get more exposure this way, rather than as an "answer" on a 3 year old thread.
In the interim here's a link to get a free copy of the CV-491 service manual. (Scroll down the page to find the model number entry)
Don't know if it is the same as a CV-491S but the Troubleshooting section describes how to perform a leakdown test which may help.
Cheers
