  1. 96 Yamaha Big Bear Replacing carburetor jets

    Also there is a brass slotted head screw I believe on the bottom of the carb., try turning it all the way in (keep track of how many turns) and then back it out 2 3/8-2 1/2 turns out for starters.

    There should be a thumb screw on the carb to adjust your idle, might try that and see if it helps.

    I'm in the process of cleaning my original carb right now as like I've said before I have had two Zoom Zoom carburetor's and nether one would work. They seem to stall out when you try to give it gas, pops, bangs, stutters, etc. and then if you keep feathering it, it might finally take off. I'm not a fan of Zoom Zoom to say the least. I didn't have any problem with the Co. in replacing the carburetor it's just that they don't work the way they should.

    Thanks for the reply. One other question that I forgot was do you know if the jets, etc. from the Mikiuni will fit in the Zoom Zoom carb. or do they have their own specks.?
  5. I have a 96 Yamaha Big Bear 2x4 with a 350 engine and have replaced the original carburetor with a Zoom Zoom version twice to no avail. I am thinking about rebuilding my original carb. and was wondering if the same mikiuni jets that you would use for a snowmobile will work in the ATV or are they different? Thanks

  7. 1996 Yamaha Big Bear - Runs Rough

    OK where on the carburetor should I look for the screen? I checked the break down on the carb. and couldn't find anywhere where it showed a screen or listed it in the parts inventory.
  8. I have a 96 Yamaha Big Bear 350 2x4 which up till yesterday was running ok. However out of the blue as I was going through the field it started missing if you tried to go over half throttle. It will start and run up to about half throttle and then it starts to miss. I changed to a new spark plug thinking it maybe had some carbon buildup but that didn't help. I put a new filter on it this spring as I do each spring but it seems more like something electrical in nature. Anny ideas? Thanks
