Review on 🛵 YAMAHA BIG BEAR 350 4X4 Carburetor 4WU-14901-00-00 – 1997 1998 1999 – Genuine Replacement by Tre Boyer

Filled my old Mikuni carburetor. I figured that either the float was bad or the float valve/seat needed replacing. Since this carb was so cheap, I decided to give it a try. It arrived on time and the quality seems ok and it fits well and has no problems installing it on my '98 Yamaha Big Bear but I can't get it to work properly. When the choke is fully closed it idles but I have to use the full choke to get it moving and then it stalls when you release the throttle unless you remove the choke. I increased the main jet several sizes but the problem still persists. I'll probably go back to my old carburetor and fix the float and/or float valve issue. I would not recommend this carbohydrate.
