Question about Garden
My echo cs-300 will start & run fine for a few seconds,, then will die. I suspect the gas vent is plugged. I see the hose,, it goes way back into the motor. How do I get to the end? I suppose it has some sort of "duck bill" fitting.
Find the fuel air mixture screw located by the carb and turn it so the moter starts to slow down then turn it so the blower runs smoothly this should keep it from dying out

SOURCE: Oil causing a problem?
Sound as if you have too much oil in the machine. Anytime you see white or lite gray smoke it is a sign of too much oil. Before you go through the routine of cleaning the oil out of every nook and cranny, try unscrewing the spark plug and clean it with a soft rag. It would have oil on it preventing the machine from starting. If this does work and there isn't a lot of oil in the gas tank now, just continue running the engine until the smoke clears. It won't hurt anything. But if cleaning the plug doesn't help you will have to empty all gas and oil from the gas tank, refill with new gas, squirt a little gum out carb cleaner in your carb to remove any oil there (this can be done when you try to restart the engine). Remember, when you are mowing grass if you are mowing on a hill) of any knd, make sure to turn the mower so the gas tank is on a higher level than the oil.

Was gasoline left in the tank during off season? Sometimes gas will break down and clog the jets in the carb. The priming bypasses the carb so when you put fuel in by pumping the bulb it runs, but dies becasue no additional fuel is coming through the carb after the primed fuel is burned off. Sounds like you need to clean the jets in the carb and in the future, use Stabil in gasoline to keep it from breaking down.

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.
