i am figuring that the needle and seat are to blame for the gas i have pumping out the two over flow lines and filling the crank case on my 2002 zl550. now the question i have is how do i get the pin out that is holding the arm the is under the needle. i have mikuni round slide carbs, with duel indivudal floats that are mounted in the bowl. it is pressed in or something it will not push out. will i have to drive it out or am i missing something?
