I'm in Apple Valley, and I am running the JD Jet kit : 170 main, 48 pilot, Blue needle in 4th from top groove. Mine was so bad when I bought it new that I waited until I got this kit before I got to break it in. The most frustrating 2 weeks ever! :crazy: but it was definately worth it. No bog, no backfiring, and tons of power. :ride:
