1. It's not helping matters to be pulling on the lanyard while trying to start it, reason why the beeping is all over the place. 2. Possible battery issue, either going bad, not holding a charge, or needs a full charge.
Check the battery voltage while cranking with the spark plugs in place. My XP with a good battery dropped to 11.6 volts while cranking. You can remove the plugs and crank it to see what it does with no compression. Usually turns over much better but that doesn't prove anything. Kinda like starting the ski in the driveway then taking it to the water. Good Luck !!
Jet pump is out and the starter is burnt from trying to free the locked up motor. No history was told it shut off and didn't start when bought from previous owner.
