I have a Trimmer SS30. When I run it I must keep choke at half setting with full gas. If I put it on run it stops. After awhile even on half choke it stops.

After you start it and are in the second stage of the choke (half choke ) let it run for awhile until it warms a bit then try openning choke and going to full throttle.

The gas is going into the the crankcase. When the piston goes down it opens the ports and allows the gas to go down untill it could fill the crankcase. Start by blowing compressed air into the spark plug hole and allowing the piston to go to it's lowest position. This will usually remove any liquid gas from the crankcase. Next get yourself a small spray bottle and fill it with the same gas mixture your trimmer uses. Now you can spray a small amount into the spark plug port, replace the spark plug, full choke and pull till it pops. set to half choke and pull. I have also sprayed into the carb but you must open the throttle to allow the gas to enter the combustion chamber. Spray,close throttle,pull choke and pull. You may need to do this a few times for it to start. After it starts let it run at half choke for awhile until it warms a bit then open choke and go to full throttle. If this dosen't work it's possible to have other problems.

I have the same problem. It will run if I put it halfway between Half Choke and Full Choke. But, just dies if I put it on Run or Half Choke. Don't ever loan your WE to anyone, They might just try to run it on straight gas--That is what happened on another week eater that I had.

Give lots of details when describing the problem. When it started, was the choke on? If the choke is on, try starting it with the choke off, or starting it with the choke on and immediately taking the choke off when it starts, but keeping your fingers on the choke so you can turn it on again if the motor begins to die. As others have described, you have a problem with the mixture screws not being set right or the carb diaphram being damaged. Your owners manual may tell you what settings to start with on the mixture screws, or you may be able to google the model number and get the manual online if you don't have one. At this point you should have taken the carb apart to look for problems and blow out the air and fuel passages. You are making progress. At least you know that it is getting spark, and getting gas. I am not familiar with that model, but many of them have three settings for the choke, fully on, half on, and completely off. If you have that type, after it starts and dies, take out the plug and dry it, then try starting it with the choke half on. You will need to clear out the excess gas while you have the plug out.

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.

Most likely carburetor needs adjustment.

It's starving for fuel. What is it? Sounds like the jets are plugged in the carb. or possibly water in the gas. Remove carb., disassemble, clean and put back together. You should get a rebuild kit for it first so you have new gaskets, etc. when you reassemble. It's a little more complex than I can put in words for you here.

Also empty and clean fuel tank too and start with fresh, clean fuel.

Many times with a gas mix, after sitting for a while, the mix separates and gums up the carb. Taking the carb off and soaking it overnight in a parts or carb cleaner and running carb cleaner through the tank and gas lines will cure this.

My straight shaft trimmer will idle but dies when the I pull the trigger.

Carburetor is out of adjustment. there are two carb adjustment screws on the side of the Carb. they require a special tool that is only $5 from your local mower repair dealer. those screws are the idle and Hi speed mixture adjustments. the carbs on Ryobi are set too lean. turn counterclockise to richen the mixture. just turn one eigth of a turn at a time. start w the hi speed.
