I have a 1985 CJ7 that misses when the engine is warmed up. I have installed a Weber 32/36 carb., Jacobs Ignition system with the super coil and have disconnected most of the Emissions system. The fuel pump and filter have been replaced and it has new spark plug wires and NGK plugs. The problem is getting worse by the day. It misses going down the road at high rpm's and is really bad off idle. Sometimes I just don't know if the Jeep is going to make it across the intersection. It does not happen all the time and it seems to come in cycles. The Jeep has the stock 258 six. I took the carb apart and couldn't find any dirt or trash in it and am I wondering if this is a needle and seat or maybe a float problem. All of the aftermarket items are about six months old and I installed them myself. I am really stumped on this one and wold really apreiciate anyones help. Thanks.
