Personally ive not tried the jd needles but from what i can gather results are mixed for the gg engine.a lot of guys are getting good results with suzuki ned?/nec? or yamaha n3c? needles.the ? is because the last letter in code is diameter and varies for different capacities/carbs/setups.find the stamped code on your needle and post.
Also worth looking thru the jetting database on this forum for equivalent setups.be wary of different fuels/altitudes/climatic differences in here though.fwiw im running nech clip3(half clip variation of nedh)but mines a 13 200(1 wheel drive!).also there are 2 pwk carbs,as1 has a screw top,as2 has two philips screws holding cap.the as2 jets leaner so its a good idea to post that too.
Once you post your full setup,some of the jetting gurus will most likely chime in
