Decel Popping

I have non. programmble cdi, HW jet kit and Muzzy exh. I am at 5400 ft elev. I have it set up w/ 142 in the front, 144 in the rear, needle in the 1st position, and the fuel screw is at about 2 1/2 out. It runs pretty good and I pulled the plugs, they are brown so I think they look how they are supposed to? My question is how do I tune out the decel popping?
Thank You for you help!

Move the clip to the second position first and turn the screw out three turns.

Brett,
Did you turn the idle-mix screws out 3 turns also?

I did not try the air screw yet. I can not seem to find a exhaust leak. My stock and Muzzys
were both having this problem.

You may have to go bigger on the pilot jet. A air/fuel ratio gauge would tell you exactly what the issue is.

Do you know what the stock pilot # is?
Thank You

Hate to say it...but I KNEW that was where this thread was going!....A/F TODD!!!!

I kept hearing him talk about the A/F meter...and doubting Thomas here did not believe him. Well, I am no longer an infidel, and I don't see how "I thought" I was tuning before.... fact of the matter is I was way off.... and anytime I do any mods or carb changes on my Teryx and other ATV's...I will be there with my A/F meter to tune those carbs. Found out either my hearing sucks or my tuning skills suck, oh and I was converted by HW.

I would not mind letting you use mine but I use it too often to lend it out. Like Teerible said, once you get one you will use it more than you think and you will be spot on. Very hard to diagnose a fuel problem when being rich and lean can cause the same result. Example, get it too lean and it misses and when you get it too rich it misses. They are different kind of misses but unless you deal with it alot they both sound the same.

Hard to know what to do when this happens and the gauge will tell you in minutes. Not picking here but if you had one, we would not be still discussing it, you would have had it fixed and enjoying your new toys. Don't get me wrong, I will help you until the cows come home but I know how frustrating stuff like that can be.
