You would think so. But it takes less than 10 seconds(maybe 5) to pull the hose and slide it on the carb. If you lean over the right side fender to "look at something" you would be pretty well hidden to do this. Hell, maybe it was done while I was standing there looking at something else.
When I opened the hood to look for a problem, I immediately spotted this. This is NOT a mistake that I would make. Granted, I can make a lot of mistakes, and I do. BUT NOT THIS ONE
There is the possibility, as it is so obvious, that it was intended as a joke. Knowing I would spot it fast. But it is not a joke on a car I worked the last 42 months, working on most every day
