Weed eater stalling

replace the idle control sensor to get an idle speed above 800
run the fault codes as there may be more wrong that need fixing

It should run ok after warming up. After starting it, let it run for a minute or so and then try gradually opening the choke. You might try increasing the throttle setting at the same time. After the motor is hot, if you have to have the throttle setting increased in order to keep it running it means the idle setting needs to be increased, usually by turning a screw to keep the fuel valve from closing so much, or that there is a problem with the fuel flow......like a clogged jet or fuel passage in the carb.

It can be low fuel pressure issue or clogged fuel pump.Or its engine related issues,---------------

These details will help.
Thanks.

Take out carb and spray with carb cleaner through and into all portals. Blow out with air compressor.and reassemble.

Adjust idle and low and high mixture screws according for proper operation.

have to adjust the high on the carb. should have, 3 screws, 2 that are together is your h for high, and L for low. the one by itself is for idle. when mackine is running, squeeze throttle and adjust the high til it clears up, if it stalls real fast, back counter clockwise while off, and try to restart it, if worse, go the other way. i do mine by 1/4 turns. keep count of turns in case your going the wrong way! hope this helps!

THATS WHAT IT NEEDS YOUHAVE TO TAKE IT TO A SHOP FOR THAT

Try spraying some carb cleaner into the intake while its running - with the air filter out..
If that doesnt help & if it sat for a long time without being run - you might need to get the carb reuilt..

Hope this elps !!
rate me good ;o)

when i give it gas it stall

A couple of things may work...
Make sure you have the correct Oil / Fuel mixture, if it is incorrect the motor may have problems running.
Also take off the bottom where the cord is wound up, make sure there hasn't been any grass get wound up inside it, this will cause it to stall out on high RPM.

Common issue at the shop (i'm a ford technician), here is what I do to correct it.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
