Just purchased a 1984 gas club car. Drove about three blocks then it would stall out, I would choke it to get it moving again it would go around 100 feet and it would stall again. There is a real rich exhaust smell too. Rode on cart for 5 minutes and my clothes smelt like I was outside snow blowing the driveway. After I parked it in the garage smoke came from tailpipe for around a minute or so. Any ideas?????
