  • Carb Issues?

    I've got an '89 Festiva, carbed, 4 speed. 138k miles. It's been hard to start when cold since I got it, usually you have to pump the throttle three or four times, and start at half throttle to get it to start in the mornings, but it fires right up once the engine is warm. I'm pretty sure this is a choke issue that I have yet to figure out.

    Recently it's been starting in that fashion, and in addition, maybe one time our of twenty, it will idle rough and die, and stalls as soon as I try to take off it will die. It usually idles well enough, so I'm thinking I can rule out a spark or EGR problem. I'm thinking its starving for fuel, it will not respond to throttle until after half throttle or so, and the car will buck in all gears at steady throttle. Like I said the problem is quite intermittent, the car runs great most of the time aside from cold starts. (I drove it 600 miles to a meet yesterday without incident) I should also mention this is the first time I've really driven this car in cold weather, it sat all winter. I'm crossing my fingers that it's just a clogged fuel filter, since it has not been changed since before I got it last summer, maybe never, :shock: so I plan to do that soon anyway in the interest of maintenance if nothing else. If a fuel filter does not correct the problem, does anyone else have any idea what is causing this.

    Had the same on my 89, I adjusted the butterfly as far as i could to get it to close , but it still opens too fast on cold start , so i put a toggle switch on the red wire that feeds the choke heater and leave it in the off position till engine warms up,,,i did this several weeks ago and this cured my cold start/bogging/hesititation till engine warms up problem...

      Owner's manual says to pump gas 3-4 times and hold pedal half way down to start. Your car seems to behave normally. Mine is the same. Mine starts right up when I plug in the block heater for an hour before starting. I checked the electricity consumption of the block heater and it's costing me about 3 cents to use it to warm up the engine.

        My carbed car I press the pedal to the floor one time to set the choke and it starts right up.
