If the engine runs as you say...the only thing it can really be is a broken governor, it must be replaced in order for the engine to run properly

2003 Kia Sedona what is the RPM supposed to idle aton cold start an in warm weather


Idle speed depends on a number of factors; for instance it may idle faster when the air conditioner is on. Instead of a fixed idle speed, as in the old cars, the engine computer sets the speed to whatever is needed to run any accessories and maintain smooth operation, but generally not more than that. That's under normal circumstances. There are several failure modes that cause erratic idle speed; usually the engine will also run roughly.

A friend of mine gave me a zr series ,625cdv homelite weed eater and I can't figure out how to adjust the carb. Bought a new primer bulb it crank and run for a little bit but I have to idle it high


Screw in the HIGH and LOW needle valves. Then turn each one out 1 full turn, That should be a good starting point.
After engine is running Run engine at Full throttle. Loosen HIGH screw until the engines RPM slows a bit. When that happens Turn screw back in until it revs high and then just starts to slow again. You do not want the engine to run at it's highest RPM or it's not getting enough Lubrication It need to run Rich, that's why you screw the screw in a bit after the engine has reached it's highest RPM. Let it idle down . Then Accelerate hard, if it hesitates, loosen or tighten the LOW until it accelerates quickly with no hesitation.

Ryobi 725r trimmer carburetor adjustment


Turn both low and high adjustment screws carefully clockwise all the way in - do not overtighten.. Then back out each two full turns. Set the idle speed control for highest setting. Prime and start and let it run and warm up for about 15 seconds - then lower the rpms a tad and then adjust the low end screw for highest rpm. Then reset the idle to lower reasonable level. You may have to go back and forth with those two adjustments till it runs fine at low idle speed..

Then accelerate to highest speed and set the high adjustment for highest rpm. Then go from idle to high speed. If not smooth a small adjustment on the high speed screw is in order. Keep doing that until you get a nice smooth transition form low speed to high speed.

Engine runs idles great slow speed until throttle up then shuts down


Depending on where you are, you could be getting carbeurettor ice. It's rare, but has happened to me with a 35hp outboard in early morning when temp was just above freezing but humidity was high.

At idle left cyl misfires. Remove right plug wire at idle and bike dies. hold idle up and remove right plug wire and bike stays running. runs good on the road as long as you are in 2nd gear. Has good fire...


The two carbs are not balanced to each other. Balance as follows; Start the bike then increase the idle on the left carb to a high idle. Now unplug the right cylinder and the engine will slow down some. Now slowly turn the idle down on the left carb until the engine just dies. Hook up the right plug wire then do the same proceedure for the right carb. Now both carbs are balanced. Hook up the left wire and start the engine again. The bike will be running faster than you want so now adjust the idle screws on both carbs equally to get the desired idle speed. Please rate my answer. Thanks.

2000 buick century idles fast when cold I let it run for couple minutes turn off start back up and idles just fine


Is the car idling faster than it has in the past when cold? The car is designed to idle a little faster than normal during warm up, to warm the engine quicker, and to keep it running. The fuel/air mix richens, (more fuel in the mix than normal), during start up conditions, and then as the engine warms, it should idle down to normal. Have you allowed it to continue its fast idle to see if it idles back down? Your post indicates that you turn it off and re-start to prompt the car to idle down. You have electronic fuel injection. The system adjusts to the prevalaint conditions to give you the perfect mix regardless of the condition it is presented with. It gathers input from a series of sensors that detect engine temp, outside temp, humidity and air pressure, to deliver the mix it needs. Often, when the mix is off, it is a result of a faulty sensor. This can be detected by running a fault code diagnostic check. You can have this performed for free at most national parts chains such as advance or auto zone. Other factors can cause an improper mix, such as dirty or clogged injectors, and/or a dirty air filter. Good Luck! I hope that you find this to be very helpful!
