John Deere #180 won't start through compression stroke

[GregTD]

I haven't run it for 2 months. It wouldn't start, so I added a jumpstarter. It turns until it hits the compression stroke, and then stops. When I turn it by hand the the compression part seems really hard to turn through.

Is there something I can easily disassemble and clean / WD40?

Thank you

Remove battery & have it load tested at auto parts store. Your description of engine rotating is normal. Engine cold adjust valves. Post all numbers from engine.
