I got my blaster running today and i took a trip around the yard and pulled into the garage and i got off and let it idle and then noticed a puddle of something immediately on the ground and upon further inspection i found out it was fuel and it was coming out of all 3 overflow tubes so i quickly shut the fuel off and it quit. so i pulled the carb out and cleaned it and everything looked fine. i put it back in and it did the same thing. the only time it doesnt do it is when i hold the float up but as soon as i let it down it starts flowing again. please help. i dont want to buy a brand new carb unless i have too. but if you have a used one laying around that is in good condition then let me know.
