My 2004 rancher 350 always ran good but never had the low end power of my buddy’s 350s! She’s still quick and can keep up with everyone but I couldn’t spin 24s as good as they could spin 25s! I have 25s on er now and she had a lot of power loss so I’m wondering what could be wrong because she suffers! My friends dad cleaned the carb and found no dirt or damage but after he put it back in he must have got dirt in it because my bike shut off when I hit water and died and wouldn’t move under her own power without choke on! Took it apart and found dirt, cleaned it out it back in and she died again in water! She started to shut off while idleing just like I hit the kill switch but she started right back up but runs really rough which she never ever did before! He did break an o ring on the pilot screw but replaced it when he cleaned he carb! So I’m wondering how to get the bike idleing good again and then the primary problem of not as much low end power! Going across bog and when she hits wet soupy bog she just can’t paint the tires in secound gear!! Any ideas?
