check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes. if that doesn't work have the carb repaired at a service center or replaced.

Hi imella96

Remove your spark plug and check to be sure you are getting fire at the spark plug.
You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
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 instructions 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.
Once you have your carburetor rebuilt that should solve your problem.

Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use compressed air to blow out all the fuel and air passages.

Hi r13santana...

Sounds like you have dirt/debris in your carburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Also check you fuel line condition after a while they will degrade and need replacment.
Make sure you are getting spark at the spark plug, to do this:
Remove your spark plug and check to be sure you are getting fire at the spark plug.
You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater is over a couple of years 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.

What powers carburetor solenoid on a craftsman model 316.711200 weed wacker


The power source comes from the ignition module(coil), Power is stepped down internally in ignition module to something between 9v and 18v(can't remember exact voltage for sure at this time).

I don't recall seeing one on that model go bad. usually it ends up being the carburetor. Or incorrect spark plug that is the culprit(If cylinder is O.K. and you have spark).

Hope this helps.

What is the best gas treatment for running and storing my lawn mowers


yes, starter fluid will work, but I recommend getting a bottle of Carb Cleaner. It's easily purchased at any hardware store or automotive repair place, and it works really fast on any gunk in a carburetor. A few solid sprays with carb cleaner and wipe it out with a paper towel, and the thing will be spotless.

Craftsman 25cc Convertible weed wacker


Yes, a simple carburetor cleaning will do the trick. Disassemble the carb. and spray with carb. cleaner. Make sure the small screen is free from debris. Clean the small portals with a Den Tek Brush (http://www.dentek.com/shop.php?target=products&product_id=7). They work great for this job. Reassemble and start.
If this doesn't do it, buy a new carb. kit and replace all appropriate parts.

Will not start normally


Your carbeurator has crud in it from leaving gas in it over the winter.
You may be able to clean it using a carbeurator cleaner spray which you spray into the air intake after you remove the air filter, OR by using a gas additive such as seafoam which will clean the carb. as it runs. If you have any old gas in the tank of your weedwacker, discard it. Same goes for your portable gas tank. Gas deteriorates over the winter.
