I just picked up a 2004 Suzuki ltz250 that I knew needed a little bit of work (carb issues and valves seals-hopefully) I cleaned the carb after I got it and it runs a lot better but it leaks fuel from a weird spot can’t tell if the float needs adjusted or what but the last guy tried messing with it and he didn’t seem to be all there lol could this be from the needle and or seat being worn? A new carb is like $50 if I have to buy a part for it I’ll just buy the whole carb let me know what y’all think.

If that is an EBay knockoff carb, then that’s probably the issue. Those things are junk.

If it doesn’t have Mikuni stamped on the side near the throttle cable, then it’s not OEM. Those are around $400 new, knockoffs are around $50.

Rather than paying that ridiculous price, most people replace it with a used FCR39 from several 450 models. It’s not simple, but there is tons of info here on it if you search for it. Best mod for the buck on the quads.

They normally flood out of the bowl vent, but it may be plugged.Leaks are usually the needle and seat or the O ring under the seat.

It’s stamped with mikuni
I can’t for the life of me find a good tutorial that’ll show me how to adjust the float without the special tool I know somebody somewhere has some input I was able to do it with any other carburetor on any other machine even the ol Holley 4 barrel

The float level isn’t really that crucial. Most carbs are: turn it upside down and set the float level with the bowl rim. It sounds like you have a clog internally in a passage.
