I love big oil they have paid me to operate rig for ten years of my life, now i am moving on to better "big oil jobs", they are also very nice to stop at whe my low diesel light comes on or when i need new shoes with petroleum/rubber soles i just love the shit out of them!Carburetor that get 100 mpg, patented 41 years ago should have an expired patent by now?
Of course BIG OIL bought the patent and shelved it so oil dependency would continue.
Now 41 years later I am wondering how difficult it is to go back through old patents and sort the junk that should work from the gold that does work?
Can it be done online or must one go to an office and look through cabinets or hire one of the patent office employees to search?
Yes, like anyone else I would like to make some money but more so, I am fed up with BIG OIL!" id="yui_3_9_1_9_1398908969550_556" style="margin-bottom: 10px;">When I was 7 years old I heard some adults talking about the carburetor that was invented that if installed on most any car would get 100 miles to a gallon of gas or there about.

US patents issued prior to 1995 expired 17 years after issue. Things after that expire 20 years after filing; things pending in 1995 expire 20 years after filing or 17 years after issue, whichever is later.

All US patents are available online at uspto.gov. Recent patents can be searched by keyword or class or inventor or owner. Earlier patents can be displayed only by patent number.
google.com/patents has a somewhat better search engine and includes many (if not all) older patents. There are many other patent-searching tools online or available through a searching service.
BTW: There are also "patent repositories" ("Patent and Trademark Resource Centers") scattered around the country, in which copies of every US patent and US registered trademark can be found in printed form. They are arranged in "shoes", not cabinets, sorted by class and subclass, and by date. Good luck with that. There are hundreds of thousands of patents related to internal-combustion engines.
