02 200exc jetting problem

[agitt73]

ive tried a 178-185 mains and all of them have the same plug
reading white with ash deposits i have a 45 pilot ddk 3rd clip
is this normal or do i have a posible high rpm air leak
at idle through half throttle the plug is light brown like
coffee with creamer its been like this since new

ive found the problem a little peice of plastic
in the hole on the rear of the carb were the
air screw gose through
