Ok, I've read the needle decoder on JustKDX, but I cant understand any of it. I've also searched, but I couldn't find anything of help. Right now I have the stock 220 needle: R1173L. Clip in top position. It is rich at 1/2 throttle. My question: all I need to know is what is the number of the needle I need for a one step leaner needle? R1172L? In my dads 91 200 he has a R1172N, will that work?

Mods and stuff:
FMF KB 30
RAD valve
152 main
40 pilot
1200ft elev
80-90 degrees F

Please make it basic, I am still learning about needles and I find it difficult. Thanks.

simply put the n needle is longer,with a smaller (richer) straight section I am surprised that you are running rich at 1/2 throttle with the needle clip in the top position, Since you have an 1172n needle give it a try and keep notes on how it works.
