Did you use an ammeter for the parasitic load test?
Do you have a battery charger? Charge it up. Try to start. If it drops below 10V, replace the battery.
When I jumped it the bolts were hovering around 13v but it still was hard to start. Got it started left it running for a few minutes, turned it off and working 5 minutes battery had dropped to 9v. The battery is brand new.

So I’m not sure what it is but the started sounds like crap. It’s clattering and really struggles to get going.
