There are a few things you can do to help you out with the settings. Before removing any adjustment screws, slowly and easily turn them in until they just pouch their stops or seats. And count the number of turns it take to turn them in. Then after cleaning the carb, set them at those same initial settings again and that will put you back to the initial carb settings. Also, some folks do the usual disassembly and spray the fuel bowl clean and think they rebuilt their carb. But there are so many other things that needs to be disassembled and cleaned. Most carbs have three circuits in them. That is a choking system, an idle system and of course the high speed circuit. And each one of them can and do get clogged up with bad gas deposits and dirt and things in the gas and air over time. So you have to get to those areas to clean them. And that means a total disassembly and carb sprays and compressed air to make certain the small pin holes and slots are opened again. Failure to do that, and you might as well not even try to clean the carb because it will not work properly after a meager attempt. JMHO!
