Coleman UT 400 has a strong sulfur/emissions smell from exhaust all the time.  Kind of like it’s running rich and a catalytic converter is trying to make it run cleaner so it smells bad. Also misfires when warm. Idles fine. Full throttle fine. In between it cuts out. Do these have catalytic converters?  Almost acts like it might be clogged if so.

      I have the factory service manual available for the Buck 400. Just send me a message with your email and I'll get it to you. Although there is no charge for this, it would be great if  you would visit my website where you could donate any amount to help do things like this with others who need it. Again, there is no charge for this manual, and no obligation to donate. But if you did, I would thank you for sure. Have fun on the trails. www.warriorsoffroad.com

      Snow Blade for Coleman Outfitter 550?
      By Alien10
      I'm thinking of buying a snow blade for my Coleman Outfitter 550 (Hisun with Coleman stickers).
      Has anyone purchased a snow blade that can offer the make and model they bought and any comments, pros  cons etc.?
      Not 100% sure I'm going to buy, as the selection of blades for this model seems a bit thin on line. 
      Thoughts and comments welcomed.
      Thanks in advance.

      Coleman 550 Rear Differential Leak
      By Tejun
      Neighbor rode their Coleman with the park brake apparently not fully released. Needless to say, things got pretty hot and even started smoking and the smoke was definitely gear oil smell. Looks like oil is coming from the area just behind the disc for the park break. Looking at parts diagram, there is an oring behind the nut/washer that attaches the flange to pinion shaft. I'm not finding anything on YT that would help with disassembly. Anyone have some experience with removing rear driveshaft ?
