My Maverick was running fine up until a couple weeks ago. It has started taking 4-5 attempts to get the engine going, and when it does finally get started, most of the time the rpm's hover at about 500 and then it stalls out when I press on the gas. Once I have gotten it started running well, It will continue to start up just fine for the rest of the day. Every few days it still starts up right away in the morning, so I've been hoping that it's just getting used to the switch from cold to warm up here in Minnesota, but that's seeming less like the case as it drags on. I put in a new fuel filter and have sprayed the carborator with carb cleaner, but neither have done much to help. I'm guessing that the carborator probably needs to be rebuilt, but I figured I would get some more knowledgeable opinions before I attempt taking it out. I also changed the oil about a week before the problem started, but I donno if that could be related at all. The car is a '76 4 door with a 250 straight 6. Any help is much appreciated, thank you!
