358.799110 trimmer will not run with choke off

Craftsman trimmer model
358.799110 trimmer will not run with choke off. Starts with full choke and runs for several minutes at mid-choke and then quits. What is wrong?

    Using the trimmer two or three times a year, I have to prime the carburetor to get it started. Then after starting, I have to leave it partially choked to keep it running and even then it doesn't run very long. I am currently using a 40:1 fuel mixture.

    have you got the right mixture of gas and oil? If your mix is too lean it will take a lot of "choke" to enrich the mixture. But it still won't run if the mix is wrong

You need to rebuild the carburetor. You will need to go to an outdoor power & equipment store of some kind to get a carburetor kit for your specific trimmer. It will come with various gaskets, (some of which you won't use), a needle valve, and a small screen that goes in the carb. Replace all old parts with new. New primer bulb is sold seperately. When you have the carb. apart, you will also need to clean the small ports with a Den Tek Brush (used for cleaning teeth). Use carb. cleaner when cleaning.

Sounds like you will need to clean your carburetor.
Be sure to use compressed air to blow out all the fuel and air passages.
Sometimes you can get by with priming the carburetor a few times, and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
If the mower/weedeater is over a couple years old, then I also recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, You will first seat the jet screws and count the number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns they were in/out.

SOURCE: Homelite trimmer will not start.

Check your fuel filter if you have one, and also make sure you are using fresh fuel and oil mix...to the right mixture and not too much oil.
If the mower/weedeater is over a year old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instrucitons you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.

My craftsman weedwacker starts on full choke then at half choke it still runs but i have to really rev it and then when i move choke to off it dies


This is fuel starvation, start with easy things first, replace the fuel filter in the tank, check the condition of the fuel hoses up to the carb for splits, cracks or leakage, replace if required

Weedeater is usable and ready, don't know how to start it


I hope you have fresh gas and 2-cycle oil mixed up! They always seem to start strong and explosively cut on good, fresh fuel. :D

1:Choke on.

2:Push the primer bulb (rubber ball by the side of the air filter) 3 times.

3:Place trimmer on ground. Grasp the handle, squeezing the throttle fully in left hand. Kneel and give that starter a crisp, sharp tug with your right hand. If the engine "hits", then push in the choke until off. Goto step 4.

If it does not give a hint of life, repeat the tug on the line 2 more times. If it STILL does not start, check for a distinct odor of gasoline. Likely, at this point, it is flooded, proceed to step 5.

4: With choke now off, continue to depress the throttle fully and give it another sharp pull on the starter. If it starts and revs? Let it idle for a minute to warm up, then go to work!

5:With choke OFF, press and hold throttle at full. It may take several pulls on the starter rope to see any life. If after 10 pulls and there is still no life, and still smells of gasoline - time to see the Ex about getting the trimmer looked after for some TLC. :D

32 cc craftsman trimmer starts but will not run at full rpm


Air fuel mixture problem,,,you need to have the filter pulled out and cleaned. Check fuel system for debris and clean, that includes all the fuel lines and possibly disassemble carb and clean and reassemble.

Primer bubble is cracked.minimal fuel is getting to carburator. when it starts it will run a few seconds then cut off.Won't run except in full choke. Please Help


The primer bulb needs to be replaced. It is introducing air to the system and not allow fuel to flow. Replace it and check the fuel lines while you are at it.

Runs on choke a little


sounds like the carburetor has gummed up a bit, and may need adjustments - or, the fuel pickup in the tank has come loose [i.e.: deteriorated fuel lines] - also, make sure your gas mix is FRESH. if your gas mix is more than 2 months old, dump it

32 cc string trimmer will not run


It sounds like you need to adjust the fuel mixture screw in the carb. To do this, while it is running adjust the screw in either direction until it runs properly without the choke.

Starts easy and idles well with choke on full. Dies in run


Open the air adjustment screw a bit more. There's usually plastic piece that stops you from opening it up. I always break off the plastic.(damn engineers) It's not getting enough gas.

Craftsman 32cc Trimmer Runs with choke at idle, then stalls


Sounds like somewhere you have a air leak. Most likely it's somewhere near the carburetor intake or maybe the carb itself. Could be a line from the primer if it has one and i do believe it should that could be leaking or loose. Good luck.
