Check the deck belt pulleys. Sounds like the belt may be too loose.

Try disconnecting the damper (small shock absorber) and see if symptoms change.

Its running too lean on the carb mixture, you need to richen up the H screw on the carb, if not marked it will the adjusting screw furthest away from the cylinder, this will increase fuel to the engine if turned out ( anti clockwise ) you will be to purchase an adjustment tool, this is because there is no slot in the screw, it has a spline so the tool has an internal spline to fit the adjuster, the are readily available on e bay, once you have the tool, unscrew the adjuster onlt 5 minutes on a clock face.

Check the spark arrest screen is clear.

Hi,
If it is only running high at full choke - then it is not getting enough fuel.
You've cleaned out the whole thing - so it's not air that's the problem. It's running - so it's not a spark problem - it's a fuel problem.

If you have a fuel filter - change it out or clean it properly. If the fuel line is clear, then you need to adjust the running setting of the carb - there are usually 2 setting knobs -one for idle - one for running / mix.
You need it running richer till you get it going - then trim it back to stop it smoking and get a good rev.

That would be an operator not in seat detected. Check seat switch

May need to have the unit checked. Could be something as simple as a clogged muffler, air filter, fuel filter or engine wear or damage.

Sounds like a bad switch to me. The can and do fall apart inside. Springs, sliding contacts and the parts that make the circuit.

possible drive belt slipping or transmission skipping

willie ,you are not kidding,just not explaining very well.there is no way a bolt from the chain bar could fall into the crank case. If you mean the outer casing of the whole chainsaw ,that is ok all you need to do is remove the outer case as if you were going to fit a new chain and it wll probably fall out if it has gone the other side take the recoil start off and it will then let me know please

I would check the drive belt going to rear end if not that I would check fluid level in transmission.

There is a good video on that saw being disassembled. IT is worthy to note that hard to start may be due to fuel or ignition issues. Ignition issue could be the timing on the flywheel which is keyed to the shaft and also the gap between the magneto coil and the magnet. This gap is crucial to the output of the spark wire. It does not look like an easy saw to work on https://www.bing.com/videos/search?q=husqvarna+455+rancher+parts&docid=608051851890751573&mid=F9526C9C2FA8331F27E2F9526C9C2FA8331F27E2&view=detail&FORM=VIRE Also being a straight gasoline engine it is going to have more resistance to starting due to the compression stroke of a 4 cycle engine.
