    Don’t know your altitude but 50 & 200 sounds rich to me even at sea level, and the slide is probably fluttering up and down a little, could be because of the larger hole in it and or a weaker spring.

    what cv - 40, 44 or 51?

    I'd say the 50 is too big and that's what you are feeling

    Go with a stock slide Bout $25 bucks and drop down the size of the needle- should help.
