I need some advice! I have a 93 Samurai(South Africa) with the factory carb. When I go downhill, with my foot of the gas but still in gear and when I give some gas a cloud of blue smoke comes out the exhaust. This also happens when I want to loose some speed and after about 100 feet of freewheeling in gear and then excelarate the cloud of blue smoke comes out the exhaust. I've had the Sammy for about two weeks now and everythings seems fine. It has 65000 miles on the clock.
