How can a 1986 jeep Cherokee be fixed that stalls when it is cold and the choke closes and to restart it you have to hold the choke open?
Could be 1 of 2 things: failed choke heater itself of 12vdc not getting to the choke heater. There is a relay (located on the RH fender wall under the hood) you should have 12 volt anytime the ignition is in run.
What causes an engine to only run when the choke is on is not enough fuel getting to the engine. When the choke is on a plate inside the air intake closes so the engine sucks in more fuel which makes the engine easier to start when cold.The first thing to do is if the gas is more than 15-30 days old dump it out of the gas tank and run the engine until it…
There are several systems used by Briggs for choke control. Auto choke engines are equipped with a heat sensitive bi-metal coil attached to the exhaust. When cold, the coil closes the choke plate. When heated by exhaust gases, it opens the plate. Most other models have a manual lever to open and close the choke or a primer bulb system.
The answer is maybe. Several of the makers of ADJUSTABLE chokes recommend that you do NOT shoot slugs through them- the choke has "fingers" that are spread or tightened as the choke opens or closes- and you may break a finger. Others suggest opening the choke. Myself- I would not- not that it is always unsafe, but accuracy is likely to be marginal at best, or poor.
(1) Loosen the choke cable at the cable control bracket but do not remove it. (2) Pull cable knob or lever all the way to closed position. (3) Manually close the choke baffle all the way. (4) Tighten the choke cable at the cable control bracket. (5) Ensure choke opens and closes properly by pushing and/or pulling the cable knob or lever.
Why does your jeep grand Cherokee start then die immediately when cold may die 2or 3 more times until warm then runs great?
When engine is cold loosen screws on choke cover, or drill out rivets. Hold throttle part way open, then turn the cover until the choke opens, then slowly turn the choke cover the opposite direction until the choke closes all the way. Mark the cover and tighten or install new rivets and you are done. Good luck Jerry
