Ok, to start I'm new here and new to atv's in general. I recently acquired a 1997 Yamaha big bear 350 (yfm350fwbj) and when I first put fuel in it, it started pouring out of the over flow on the carb. I completely rebuilt the carb and now it doesn't leak while riding,as far as I can tell, but when sitting if the feul switch on the tank is on it slowly drips out of the overflow.

What should my next step be to fixing this? Could it be as simple as setting the float a little lower?

Any help is appreciated!

 

Sounds like the needle and seat are worn out. Shindy kits costs less than what the dealer wants for an oem needle and seat and it's a good quality Japenese kit. 87 97 Yamaha YFM350FW Big Bear 4WD Shindy K L Pro Carburetor Rebuild Kit 18 4179 | eBay
Saw that you rebuilt it.. From what I've found float height sets at 13 mm (0.51)

 

And to set the float at that you tube it upside down and measure from the bottom of the float (while it's touching the needle) to the bowl mating surface correct?

 

Yes, turn it upside down.
