Hi yall... Noob to the forum here...and having a problem w/ my wheeler! 2002 TRX350FM Rancher 4x4. It wasn't idling very well and I began to turn the "Throttle stop screw" a bit and found a nice spot that it idled nicely at. Rode for hours and all was good..Then it sat for a few days and now it wont start..or fires up and then dies immediately. I've foolishly turned the Throttle stop screw in both directions quite a bit w/ not luck. Is there a point where it should stop screwing in or out? ...and if so... can anyone tell me approx how far out or how many turns it may need from a closed or open postition to perform correctly? Thinking about pulling the carb and cleaning it out. Just thought I'd post this somewhere before I mess things up to much. THanks in advance for any help.

you probally got some trash in the carb jets..pull the carb..clean it out..check your jets..see if they are stoped up..more than likely your low jet ( slow/idle ) is stoped up with some trash. blow it out with some compressed air...if you cant do it that way..take ONE WIRE ONLY FROM A WIRE BRUSH..and poke it through it. ans welcome to the forums !

well i killed the battery trying to start it.. and decided to jump it w/ my mower... after it sat for a while it fired right up when jumping it! just had to ease down on the Throttle screw a bit. I think i just flooded it pretty badly and got impatient... time will tell ... THanks anyways Shadetree! Love the forum!

your welcome pear..keep an eye on it..you still may have trash in the carb jets. as for the forums..yes..it's a very helpful place to come to. alot of us try to help ppl. sad part is..we can't tell everyone what thier problem is..we try to though..lol.
