G'day,
A friend recently asked me to help fix his Honda TRX300 quad. Non running. I got it back to my place, and started ripping the fuel system down. The air filter was meant to be foam, and had degraded to dust that coated everything. I took the carb out and soaked her in degreaser for awhile, but it was full of crud. Amazing how the bike ran, even badly! I adjusted the valve clearances too, they were way out! I fixed the wiring harness that my friend had butchered attaching non-fitting battery.
For some reason farmers are the hardest on their vehicles. Every instance I find seems to be just pure negligence.

It looks like you could read tea leaves from that mess.
My past neighbour is a veterinarian and he looked after my dogs just fine but with anything having an internal combustion engine? LOL. And he had many to rectify. It often wiped my vet bills clean.
Farmers call it the "service interval"
