Just purchased 1987 LT-4WD from the estate of a deceased neighbor. It started when I brought it home but dripped gas from carb overflow. I put in a carb kit and a new choke plunger. Starts and runs better, but it won't idle and after running for 2 - 3 minutes the gas starts dripping. I took it to local dealer and he didn't see anything that would cause it. He suggested as a remote possibility that the fuel pump could be over pumping. Any suggestions and comments are welcome
