Iv not tried the jd,it may be a different diameter, but if you cant get it good.....
Do you have screw lid type carb top(as1) or 2 screw carb cap(as2)?
The as2 works well with the suzuki needle nedh clip#2 (25C up) or nech#3 (0-25C)
Nech3 is halfclip richer.pilot 40/42 main 175.needles $15-20each
0-1500ft nz 70-80% humidity (your humidity/temp may be different)13' 200xc vforce3
I wouldnt say it will give you more bottom end but its smooth and progressive rather than on/off the hit.the 40 pilot is slightly cleaner,the 42 has just a bit more guts off idle.
I run 42/175/nech#3 all yr round (0-35C)
Above 30C its a smidge rich
The Ned?/Nec? tapers work well in the 250/300 also (? is needle diameter,nec'h' for 200)
