    Start with the basics then. What number of turns are you setting the low speed needle at?

    Before I pulled the carb out, i started at 1 1/2 from lightly seated. After i put it back in, i started at 3/4 (as per instructions with the carb kit). I found that the motor worked best around the 3rd full turn from lightly seated. If I continued turning, it would start to die out quicker again. After I put the carb back on, it started way stronger at 3/4 turn, but I suspect thats also due to the float adjustment
