Yeah it might not be the drain screw.
those early Rancher carbs seems like there’s a rash of float valve problems. My 02 has never had a carb problem.
All OEM parts. I take my work quads to the local Honda shop, which has always done right by me
BTW rust on the carb shouldn’t be a problem; rust in the carb is a problem
Yeah, I want to make copies of the fan connector plug and the accessory connector plug for all of the air-cooled models. So once I learn how to design parts in Freecad I will be asking for donors. I'll pay for the parts + shipping costs, but I don't need them yet... got my hands full with outdoor work right now.
