Yep, same with my dad. Once every blue moon he gets the idea that we can make something better. He starts pulling something apart, then gets bored and moves somewhere else on the machine and pulls something else apart.... When you want to get rid of pop, the best way is your local (hopefully not to local) friendly Agco dealer. I send mine for parts. He weaves all over, looks at other peoples fields, stops at the gas station for coffee, talks to everyone at the dealership, drives home, forgot the part, darn, heads back. 8 hours later, mission accomplished.
