Car Forum / Jeep / June 2007Stuck Choke?
I have a 1984 Jeep Cherokee. It will start if a spray start fluid into the Carburetor and then rev the engine for 5-10 minutes. After it "warms up" it runs fine. Sometimes I can start the engine on a hot day, without the starter fluid. If I do not use start fluid, and the engine was not warm, then I must hold the choke open with a pencil while someone else start the engine (also I have to spray some starter fluid). How do I fix the choke? > I have a 1984 Jeep Cherokee. It will start if a spray start fluid > into the Carburetor and then rev the engine for 5-10 minutes.

The owners manual says the carb need a kit every time the engine needs plugs.... A kit will fix the choke if that is a problem but it doesn't sound like it. It is pretty much impossible to toss ideas at a 1984 carb without knowing it's history. Then if it 'only' acts up when it has sat for a while, I first suspect the fuel filter might be in upside down. If this happens, the gas siphons back to the tank when it sits so it airlocks the gas line and is a real bitch to start without starting fluid. The filter has two outlets, the center one to the carb and the 'top' one to the return line. If the return line nipple isn't up top, your symptoms happen. One other is a pinhole leak in the gas line, usually near the frame where a clip holds the steel line and/or the flex lines to the tank or pump in the front. A pinhole leak will only make a stain on the line or near the clamp when it runs under vacuum, but it will let air in when it sits which will cause your symptoms.

Starting fluid will diesel, and fire on wet plugs with a manifold full of gasoline.
