Engine cranks up idles good won't accelerate

Howdy people, Was running 1/2 - 2/3 throttle when engine or exaust went poof. Machine slowed & was not running on stop. Cranked up & it idles fine with no distress but cannot advance throttle without stalling motor. Will not move from tracks. Changed brain & no difference. I am wondering if a head gasket is blowed. Just a thought no proof. Appreciate any ideas.

    I lucked out & it was not a headgasket. The main hi speed carb jet was plugged up & the idle jet was all that was allowing any fuel to the enjine

Sounds like a restricted exhaust pipe ,remove the pipe from motor just to see if the motor power returns under throttle if so replace the pipe and gaskets

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.

I have a Briggs & Stratton Vanguard 16 HP motor. It idles fine and it runs OK at high RPMS. But it backfires thru the carburetor during accelerating. Any suggestions?


On some float-type carburetors, you can adjust the air-fuel mixture and engine speed at idle. Check for an idle speed screw designed to keep the throttle plate from closing completely, and an idle mixture screw that limits the flow of fuel at idle. If your carburetor contains these screws, proceed below.
  1. With the engine off, remove the air filter and air cartridge.
  2. Locate the idle mixture screw and turn it clockwise until the needle lightly touches the seat. Then, turn the screw counterclockwise 1-1/2 turns.
  3. If your carburetor has a main jet adjustment screw at the base of the float bowl, turn the screw clockwise until you feel it just touch the seat inside the emulsion tube. Then, turn the screw counterclockwise 1 to 1-1/2 turns. Replace the air cleaner assembly and start the engine for final carburetor adjustments.
  4. Run the engine for five minutes at half throttle to bring it to its operating temperature. Then, turn the idle mixture screw slowly clockwise until the engine begins to slow. Turn the screw in the opposite direction until the engine again begins to slow . Finally, turn the screw back to the midpoint.
  5. Using a tachometer to gauge engine speed , set the idle speed screw to bring the engine to 1750 RPM for aluminum-cylinder engine or 1200 RPM for engine with a cast-iron cylinder sleeve.
  6. With the engine running at idle , hold the throttle lever against the idle speed screw to bring the engine speed to "true idle." Then, repeat the idle mixture screw adjustments from Step 4 to fine-tune the mixture .

How to adj the crab on a poulan chainsaw


if the engine is in good shape..screw in both carb jets adjusting screws till they seat lightly, then back them out 1 1/2 turns, srew in the throttle adj screw a turn and start the motor,,warning if the chain is on make sure the blade isnt likely to touch anything when the engine starts as you will have to have the brake off to get started and adjusted. With the engine running, adjust the throttle srew until it is idling just above shutting off speed, then adjust the "L" low speed jet to get the best idling speed without srewing it in much, reset the throttle srew, then , while trying to accelerate suddenly each time, open the Low jet a little at a time until the machine accelerates smoothly without hesitation. Reset the throttle srew to a position that the chain stops running at idle and check again that the acceleration is without hesitation ( usually with "L" jet about 1/4 turn out more than best idling). The high "H" jet can now be set to give the best power while cutting a block of wood.

Stihl FS200 repair manual


I just saw this deal on the Fs200 Stihl Brushcutter. Equipped with a Zama c1qs51 carb. Junk the carb. Go to a stihl dealer and buy a three screw chainsaw type carb with a high low and idle screw. The c1qs51 is junk.The three school carb will put an end to your worries. Of course change your fuel filter naturally. I guarantee this will fix the thing. I own an Fs200 and Fs250.

2003 toyota highlander will not idle, must keep foot on the accelerator to keep engine running. AS soon as my foot is removed from the accelerator the engine cuts off.


The first place I would look is the IAC motor (idle air control) usaully on throttle body and possibly dirty throttle body and one last thing could possibley be EGR valve exaust gas recir. as if it stuck open it will lean out engine.

We are facing over heating and idling speed is not withstanding machine is getting off when we release the accelerator.


Use compressed air to blow the sawdust and dirt out from the cylinder and head. Clean the screen in the muffler. Make sure that the fuel/oil ratio is correct. Turn both L and H screws in the carburetor CW until lightly seated, then back out 1-1/2 turns CCW each. Start the engine and allow to warm up. Open the throttle and turn the H needle CW until the engine starts to speed up, but is 4-stroking. The correct position is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting is started. Let idle and adjust L CW until the engine runs fairly smoothly, yet allows the engine to 'follow the throttle' as you accelerate it. Set the idle speed screw so that the engine keeps running, but doesn't try to move the chain. Hope this helps!

On November 20, I posted the original ''1995 Lumina APV quit running.'' Two trouble codes fixed later (MAP, TPS, replaced) and a trip to Mr. Goodwrench followed by an ECU replacement, It still does not...


If there is spark and the sensor is in position and secure. There is a cold idle valve beneath the throttle body. It should repeatedly click as it actuates on and off.. Theory is it creates a controlled vacuum leak until the engine can carry ttself once warmed up.. Good Luck
