    1 and 7/8ths, plus or minus 1/4th turn.

    Hopefully, you now have your reminder to turn the screws in until lightly seated and write down the measurement for future reference.

          Make that one and seven eighths turns from lightly seated. I used a table showing idle mixture screw values and picked the wrong year 50 HP model.

          Sorry.

          It was actually a test to see if Rodbolt was still sober. Apparently he is.

            1 3/4 turns is about right.
            however I doubt that's your problem.

            occasionally I have some cool refreshing beverages before keyboarding.
            gets me in trouble occasionally.

                maybe not.
                but you can get banned from a site .
                when you did the carbs, did you do the fuel pump?
