It will not turn over with starter and will not fire while pulling pull start.
The only thing that Ive tested that didnt test correct is the kill switch I read on another forum to test black and Black/white wire for continuity when in off position I did and it shows continuity like it should. Then when you slide it to run it should be open and show no continuity which mine still shows it while in the run position. So I unplugged the CDI just for sakes of doing it and the kill switch then tests correct. So where should I test next without unplugging CDI?
I can't for the life of me find the correct service manual for this unit. It's air cooled, not liquid (oil cooler tho) and every manual I find has the wrong front differential diagram (it does NOT have a 2wd/4wd shifter).
I'd be eternally grateful if someone could point me in the right direction. I can probably slog it out from some of the exploded diagrams I've found, but a good "do this, do NOT do that" manual would be a godsend.

Hey guys, Thanks for looking at my post. I haven't had a lot of experience with problems like this before, so I'm a little bit at a loss. The Quad was really hard to shift, (the dirty carb leaking gas making it idle high didn't help either). The only Idea I have would be is that the torsion spring is worn out, and that there is a normal parameter for how much it should move when those two arms of the shift shaft assembly spread apart. That's my thought. Maybe someone who has more knowledge then me can let me know if i'm on the right track 😀

Hello guys! New to the forum, and fairly new to ATVs. I've driven them, but never owned one. Now I do own one. Just picked it up today. It's a 1999 Yamaha Big Bear 350. It's been through some stuff. The guy I got it from told me the previous owner removed the front diff because he didn't want to replace the half shaft. So it's 2wd, even though it's supposed to be 4x4. Lovely. I can deal with that for now.
More importantly, I need to get it running. The carb needs to be rebuilt. The guy I got it from said he sprayed it all out and it still didn't work. I'm concerned he might have damaged it or not put all the parts back. I was looking at a replacement carb, and the OEM parts is $600. I'd rather not spend $600 if there are any other options. I have seen carbs on Amazon and eBay that are in the $40 - $100 range that say they fit. Anyone have experience with these? I'm going to get a rebuild kit for the current carb just to make sure that won't fix it.
Thats the first thing with it. Secondly, it was completely rewired. I need to find a original wiring diagram so I can put it back how it was, with a key and all. Currently it's wired with just a rocker switch. Any sources for a service manual that would include wiring diagrams?
Thirdly, is the Big Bear 350 a good atv? I picked it up for $700. It does start and run when you spray starting fluid into the air intake, so I am not concerned about the engine being bad. I plan to use it for the farm, running around and carrying things with it like minerals and feed and such. Not really for mudding and things like that. How good is the 99 350?
I am certain I will have more questions as I examine it more, but that's all for now. Thanks in advance for the assistance!
hey I'm dave westfall I'm new I just became an official member of this site a few minutes ago. Ive been crazy about quads and bikes since I was about 3 and ive always done my home work on them figuratively speaking. I would say for comparison to the common man that I am pretty knowledgeable about them. its been my passion about most of my life. I love talking about quads and bikes so if anyone out there would like to talk with me about mechanical subjects or about person experiences while riding or just shoot the breeze please feel free to chat with me. I'm looking forward to it.
