A Friend of mine just made this post and it makes CLEAR and PERFECT Sense!!!!! Ive always written a paragraph on it but this pretty much Sums it up in a nut shell.....Hope this helps

**********************************************************

Tuning tips:

1. Motor sputters when running rich.

2. Motor hesitates, bogs, or backfires when running lean.

If rich at idle to 1/4 throttle, go 1 size smaller on pilot jet. If lean at idle to 1/4 throttle, go 1 size larger on pilot. Use adjuster screw to fine tune. If rich at 1/4 to 3/4 throttle, move clip position up 1 groove on needle. If lean at 1/4 to 3/4 throttle, move clip position down 1 groove on needle. If rich at 3/4 to full throttle, go 1 size smaller on main jet. If lean at 3/4 to full throttle, go 1 size larger on main jet.

While tuning it is best to change one item at a time to focus in on variables and fine tune.

      So we have a 2000 BearTracker 250cc. We got hit by a tornado and it got flooded out. Water was well over the handle bars and it actually moved almost 40 yards by the water. Anyway, I've pulled the carb and drained the tank. New fuel and a "clean" carb. It fires right up first crank like it used to but bogs down after you try and give it any gas. Think it could still be a carb issue? Carb had a fresh rebuild in April and might have 10-12 hours on it since. After we got it out, It was never started until I took the carb off and cleaned it along with draining the tank. Carb has now been off twice with no differences. Any other ideas?
      also the water seems to never end in the exhaust. I've gotten out as much as I could but it's still steaming quite a bit like there's more in there. Could this be the problem? I've never had an ATV get flooded out like this one before. Any help or other ideas would be great. Thanks yal.

      After I rebuilt the card it seems to have a faster idle than before. I have tried to adjust the idle screw but will only speed idle up, not slow it down. What should I look for in adjustments. I purchased a card rebuild kit.

      Bought a 01 bear tracker and a trailer from a local guy last week. I rebuilt the carb 2 days ago and ran damn near perfect for 2 hours. Parked it and came back the next day. It suddenly won't hold an idle at all and pops when I'm going downhill or at a slow speed. Almost like I'm dragging the whole power train with the weight of the ATV. It still has decent power (80-90% maybe as it is now) but I can't figure out why it's popping and won't hold an idle suddenly. even with messing with the idle screw next to the bowl on the exterior of the carb. No changes. . ANY ideas would be great. I'm far from a carb king, but I've never had this issue before. The fuel was bought 2 days ago and it has a brand new intake manifold as of yesterday when I rebuilt the carb (whole rebuild kit). I sprayed around the carb and did not find any leaks. 
       
       Thanks y'all.

      My 1004 honda trx300 starts up and sometimes idles good, sometimes not so good. If bike is running and I grab the bike and shake it the bike will stall or try to stall. What should I be looking at to fix issue?

      Can anyone help with routing the hoses on a lt250 carb hose routing? Manual doesn't really specify much, and pictures are lacking in it
