To me,this explains it best. I worked at a chrysler dealer for 20 plus years as a forman and more often than not the "do it for me" was the core intention of the question. This equates to plain lazy. When i first started they would send me to factory school to learn systems involved for vehicles sold at the time. There were two types of teachers there ,ones who gave you solutions for the symtom"if it does this ,change that" and this is what i see more often as the answer people are looking for. The preverbial magic bullet. The other teacher would explain the theory of HOW it worked so when it did something wrong you could figure out what it was not doing correctly. This is what people do not ask ,"How does that work". I read somewhere in one post how the guy was afraid to tear into a 97 for fear of screwing up his vintage part. The internet is a great place for information as well as books the person using either has to determan what they need . The caburator is a simple device that pretty much hasnt changed Three circuits and the venturi theory. Yes it is old and should be treated with care but dammit dig in someone else could do it,so can you. The other thing i learned over the years is if it worked once before you can make it work again,just figure out how it works and proceed. So to the op,no there are no stupid questions, at least in my eyes.the stupid ones are the ones asking the same questions over and over and not learning to find the answers.
