My Jeep had set for 2 months before I got it and I have been working on it and now driving it. I took it on the highway last night and after getting off the highway I came to a red light. I stopped and the Jeep stalled on me. I could smell gas really bad. I tried to start it and it wouldn't start. After I held it to the floor and it started back up. Now if I'm driving it the Jeep will stay running fine. When I stop at a light or stop sign it floods out. Will Carb and Chok cleaner fix this or do I need a new carb? Please Help.
