Well this started as gas going out the air box side of the carb all the way around in that hose and dumping gas all over the machine. I took the carb apart, cleaned it well and put it back together. I then adjusted the valves to make sure everything was kosher. When I took the cap off the bottom valve I was greated by 1/2 pint of gas with a little oil in it. So after adjusting valves and putting everything back together I changed the oil. Started it up and rode it for about a half an hour. No more gas spewing out of the air box hose. Let it sit overnight and went to start it. Wouldn't start, lifted the compression release and it started. Smelled like gas coming out of the exhaust again. What should I check? What is letting gas get into the cylinder?:skeptic:

Nope not flooding on start up. It was actually spewing gas out that hose that goes from the air box all the way up by the gas tank and then comes back to just below the air box while riding. I replaced the spring in the diaphram part of the carb, made sure the carb was cleaned good and all settings were per the service manual. We have 6000 miles on this machine and it has never been a problem up until now. If the float height is messed up would that allow gas to back flow into the air chamber????

      Help with 1987 Yamaha Big Bear YFM350FWT Carb
      By ResQ91
      Hi Guys!

      New member and could really use your advice. I would have to believe this has been an issue for others but a search here came up with nothing......? (Probably me not doing search correctly)
       
      I have an 87 Big Bear 350 YFM350FWT
      The OEM Mikuni BTM carb is shot and would rather replace than rebuild.
      It is no longer made and I have had good luck with NICHE carbs so I ordered a #K-CRB-0006 This was what they said was replacement when ordered. This Carb only uses 1 Throttle cable. The Slide is linked so it uses one. (OEM had 2nd cable coming through top to move slide)
       
      Problem is when I ordered a replacement Cable from NICHE (#C-CBL-0061) the Cable wire is a little short, not allowing Throttle to return all the way down to Idle position. I called NICHE and they are at a loss. Haven't gotten back to me after 2+ weeks.
       
      What would you recommend other than a carb rebuild?
      Can I just use 1 of the OEM cables (It is the right length) and snip/disconnect the other that went to top of Carb for Slide?
      Or ??
       
      Thanks in advance for any advice you have!!

      98 arctic cat 300 2x4 hi rev choke when started
      By Its-always-something
      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
       
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
       
       
      Any help and information greatly appreciated.

      2022 Hisun Sector 550 Gas gauge stopped working
      By Clydaho
      2022 Sector 550, 414 miles on it and the gas gauge reads empty.  I topped off the gas and it didn't change.
      There is no fuse that I could find.  No access at the gauge cluster.
      Wiring on the top of the tank looks good, properly connected.
      Could the sending unit in the tank be stuck or broken?
      Has anybody removed the tank lid?  Any tricks?  
      Any other ideas?
      Thanks for any help,
      Clyde

      How to make a 1997 Yamaha Timberwolf quiet.
      By Suzukiquad
      I have a 97 Yamaha Timberwolf and it is beyond loud, is there any good options to silence them or at least make them bare able to drive. I know it has a crack in the exhaust pipe, but even with that fixed its still loud.
