Have an 83 LT125 bought not running. I can get it to start and it sounds fine -- but it almost immediately dies and gas is gushing from around the carb (I think???). Its as if there was no fuel filter and the gas is just pouring from the fuel tank ( I know from the manual that this unit does not have a fuel filter, only a strainer). Is it possible that the adjustment screws are set incorrectly and allowing too much gas to come through the system?? Help!!!!!!!!
