Ok, I have an 86 samurai and I just had an engine replacement and got one from a salvage place. I asked for the whole setup carb, intake and exhaust manifolds, flywheel etc.. so I could just drop it in and be done before the cold hit us here in Kansas. Well, needless to say it did this week. The first thing I had was that I got it in started it and it ran good and kept running better. From there about 10 mins into running it I noticed the carb was pouring fuel from the front after everything warmed up. I started looking for a place to rebuild this one and obviously no one wants to. Well from there I checked the screws holding the top and bottom half together and they were really loose loose. I tightened them and leak issues were gone. Anyways now that it is cold when I start it after sitting a few hours I have to baby the throttle to keep it running. after a few minutes it runs perfect. I also have another issue where the alternator is not charging battery due to the radio, etc.. that will be fixed this week. I was a diesel technician for a while but, I do not know anything about carbs at all.I replaced the fuel filter as well to rule out fuel problem and it helped a lot but I still have the issue of having to baby the gas. What could be the issue at hand? I am not looking to replace it fully unless there is a good carb I can get that will allow me to go up to the mountains in Colorado without adjustments on the carb and allow me to climb steep hills. Weber is also out of the question for swap as I have disliked them for years.
