In my opinion when it come to Carb issues especially running a business, there inst a lot of time to be spent on it. Although if I had to and was in your situation I would completely disassemble the Carb and slowly put it back together correctly. Sometimes there is a spring that is not seated right or the pin is to high or to low there are many videos for this on YouTube also keep in mind a new Carb is only about 40 bucks and it will save you time and trouble with problems in the future. Don't forget time is money.
