you can get a stock lt250r mikuni tm34 on amazon for 134.00 free shipping. fixing your carb is probably cheaper but Im just lettin you know what I found for ya. I just picked up a tm38 for my lt250 (zilla carb swap) and i got it for 136.00 shipped

Sorry Internet is down and I'm answering on my phone. I copy the needle/ seat issues. They're new and seating fine. The float was bent (presumably a backyard fix by the former owner) and you have to bend it so far down that it would risk stalling out on big dunes. That's why I thing it'd be easier just to go new carb. Thanks for the info guys I'll be on Amazon tonight.
