If a brake is binding try driving in a straight line on tarmac, lightly grip the steering wheel and brake firmly. The gator will 'pull' toward the binding brake. So pulling left is a left side brake and pulling to the right is a right side brake. Another test is to chock a wheel and safely jack up each wheel enough to clear the ground and turn each wheel by hand. A binding wheel will feel tighter or won't turn at all.

You can just remove the gears inside the differential and the drive shaft. Not sure you would want to do that though, it is much better to have 4 wheel drive on an ATV. The listing says is it 2 wheel drive!! https://www.motorsportsuniverse.com/listing/auction-results/192747275/2005-john-deere-buck-500-recreation-slash-utility-atvs https://tfloffroad.com/2020/08/what-happened-to-the-john-deere-buck-atv/ ..

There are a lot of you tube videos on this unit. See if any apply. It is a specialty machine and John Deere is proprietary.

Sounds like your float is stuck. Pull that carb off and clean it. Berryman's carb cleaner is one that works well. Clean the float needle and check the surface. Use aluminium cleaner/polish like mothers on a cotton swab and clean the float needle seat. It will shine up like new. Check your float height before reassembly. I do these all the time and don't need to but parts.

The engine in a 2004 JD Buck should be a Rotax 650, which is a 2 cylinder 4 stroke water cooled engine generating 62 hp. With that said, the most likely cause of oil in the air filter and leakage from the top of the motor is excess pressure in the crankcase. A cracked block is a possibility, but the most likely culprit is worn piston rings. A compression test should help narrow it down, but in either case you are looking at a complete tear-down of the engine. https://www.rotax.com/en/products/rotax-powertrains/details/rotax-650.html

what eng size does it have ?

Try a reboot. Disconnect the ground lead from the battery for 15 seconds, then reconnect and try again.

Back firing is usually a lean fuel mixture caused by partially blocked jets or badly adjusted idle screw
