i have a 2006 yamaha wolverine 450. i recently pulled the carb apart and cleaned it as it would not idle. previous to the carb clean it would start up, idle, but then as soon as it was given any throttle it would stall out. After the carb clean and the fuel tank being emptied and fresh fuel being put in, it starts and idles extremely high and when the choke is on it idles even higher, and if given throttle it idles even higher without choking itself out or stalling. i have the idle set as low as it can go and removed the plate on the carb and the throttle cable is resting against the stop. I have adjusted the air fuel mixture screw, which was 2 turns out to begin with. I opened it to 4 turns out and it didnt make any differnce to the idle. In order to get it to idle down i have to cover the air intake hole about 80% but then when i give it any throttle it stalls out.

yes the throttle cable linkage was removed, and as for the choke it idles up even higher when i open the choke, and then back to the the initial high idle when i close the choke. Some buddies thought it may be the slide sticking open or an air leak, but i checked both and they fuction properly.

      2000 Yamaha Breeze 125 slips in Forwards, runs fine in reverse
      By hengstserepair
      Howdy ya'll. I am working ona 2000 Yamaha Breeze 125. It was in rought shape when I received it and I am working through issues as they pop up. The quad had been sitting for years. I was able to get her running again, but I need your help with the following issue:
      I don't trust the transmission yet and I don't want to make problems any worse. So, I haven't pushed things hard at all. Low rpms, less than 5mph in reverse.

      Nuetral: Runs as expected
      Reverse: She seems to be driving fine at slow speeds. Going into reverse at idle is fine, coming out of reverse back into neutral won't work (the shifter is just stuck). As soon as I turn off the quad, I am able to shift around without any issue.
      Forward: It slips. It seems to only transfer power to the wheels on a smooth surface and going slightly downhill. When shifting into forward at idle, there is a clacking sounds during the transition. Shifting back to nuetral works just fine.

      Other Notable Symptoms: There was old oil in the vbelt and when I was tuning the carb, it starting blowing out of the CVT cooling vent at the front of the quad. Made quite a mess. There is positive crankcase pressure due to piston blowby, that I have not decided whether or not I am going to fix (customer budget dependant).  Since the oil was old, much darker than the new oil that is in the crankcase, I am thinking it seeped past a bad seal while it was sitting for years. The oil that was in it when I first got it had gas in it.

      Thoughts: I am thinking maybe there is an issue with the clutch. I worry about the old oil intermingling with the dry centrifugal clutch. I was thinking my next step would be to take the cover off of the clutch and inspect it.

      Let me know what you all think. Any advice and ideas is greatly appreciated. This is only the 3rd quad I have worked on and I have a lot to learn.
