I'm sick, just got my 05 Rubicon. Has HMF, 2" snorkel and jet kit. Was jetted for ~800ft above sea level. Past 1/2 throttle she overheats real quick, when I pin throttle she spits and sputters, lacks any real power. Previous owner used 160 main and didn't change needle setting. I need to know where to start. Seems like when I use choke it runs a little better, especially at higher rpm's. My elevation is ~1800 ft above sea level. I'm supposed to go ridin' tomorrow so any help would be greatly appreciated!! HONDA MECH, need your help

Is the vacuum slide moving smoothly in the carb..?.. is the clip on the needle-jet /jet-needle and is the needle in good shape ..

Wondering if it was running lean so I put a shop towel over snorkel and kept making slits in rag until it ran better. Knowing this should I just start adjusting air/fuel mixture screw. I ran it for about 25 min., I was very easy on it but temp light came on briefly twice. When light came on I stopped and it went out right away. Fan comes on in about ten minutes . Previous owner didn't mess with c-clip on needle but put in a 160 main. I'm about 1800 ft above sea level. I'm very worried about running too lean and wrecking motor, I need help.
