Hi Jerome
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 a bright blue spark at the spark plug.
You do this by grounding the plug on the head of the engine and cranking the engine or by pulling the crank rope...watching the plug for spark.
If you are getting a nice blue spark then skip A below and go to B.
A...If you do not get a nice blue spark then you may need to replace the electronic module.
Note: If you have to replace the module be sure to measure the position it is in, it is critical to starting.
Take a picture for later reassembly.
B...Also take some fine grit sandpaper (not emery) and lightly sand the flywheel where the magnet is located to clean any rust or corrosion from the magnet area.
Then follow the procedure below:

Hi
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:
Write down on a piece of paper and or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.
Mark each piece with a awl, or some kind of sharp instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using a very small shot of 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.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line/s condition...after a while they will degrade and need replacement.
Check/Clean/Replace your fuel filter if you have one.
When you remove your fuel lines from the carburetor be sure to make a drawing or take a picture of how the lines are connected to the carburetor.
Also a good time to take a picture for later reference for reassembly.
If the mower 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.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, 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.The higher air pressure is needed to blow some of the trash/debris from the fuel or 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.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
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 original position before you started.
Once you have your carburetor cleaned/rebuilt that should solve your problem.
Please take time to rate me

Take the carb. apart and blow thru all the little passaged w/ carb cleaner you probably have a passage pluged with yuck. Make sure you use new gas when you try to start it again.

Do you mean hard to start as in you have to pull and pull to get it started or do you mean hard to start as in tough to pull? If you have to pull and pull then the carb screws (gas and air) need to be adjusted. Start by turning them all the way in and the a turn and a fourth turn out and adjust from there. If you mean just tough to pull, the some newer weedeaters have lots of compression and since they come from the factory this way it can't be changed. It will always be tough to start.

SOURCE: Craftsman 34cc 4 cycle weedwacker will not start

Start by removing and cleaning the spark plug. The check out the screen at the exhaust port and make sure that it is completely free of carbon build-up. I never run my equipment out of gas at the end of a season, I usually add some fuel stabilizer to the gas and run some into the carb before shutting down for the season. Hope this helps and good luck.

SOURCE: weedeater gas edger won't start!!!!!!!!!

yes, there is a spark module, but it's highly unlikely that two would have a bad module - more than likely, it is your gas mix. it must be fresh for the engine to run. the gas we have today will go bad in about a month and a half. if you happen to live in an area that has E85, forget it. small engines will not run very long, if at all on this junk. in some areas, you can get gas without alcohol, but it can only be used for lawn & garden equipment. it's expensive, but your engines will run

Can't get it started


There still could be old fuel in the fuel lines. Try a small squirt of starting fluid into the carb. If it fires on that the condenser and points are ok. Do this at most 2 more times.

the worst thing for generator and compressors are to sit up. when you do sit them up put stabil in the gas. run it and then run the gas out of the carburator. now, make sure the gas in the tank is good and has no water or trash. check the fuel line that it is in good conditon and not plugged. pull the carberator and clean varnish out and clean jets. soak it over nite in varsol or parts cleaner. check to see if you have a low oil shut off. oil level must be correct. check your exhaust to make sure it isn't plugged. some have a little screen that get coated with carbon and won't let it exhaust.( fuel in, spark, exhaust out)

Coleman Generator starting problems


If you started it for just a minute, it never got warmed up and MAYBE the spark plug fouled. Check it first.

Sometimes one forgets where to set the choke for starting. And if engine is already warm from a short run they can be hard to start if too much choke is used and it floods... Again, when you check the plug, if it is wet this MAY be the problem.

To check fuel getting to the engine I have used an UNLIT propane torch into the carb to give an engine a mixture that it can run on without flooding. You usually have to remove the air cleaner to do this. That is a trick I have used for "cranky" engines.

Since you stired up the gas, the fuel filter may have got plugged.

Husqvarna chain saw works great until its shut off then it wont start again


A couple of suggestions:

How old is the gas in the tank? If it has sat for a year in the tank or the can, the gas won't burn as easily because of octane breakdown. Mix in newly bought gas (with oil of course).

Pull the spark plug(s) and check the spark gap referring to your manual. If the gap is too wide, you'll have a hard time starting it.
It's also a good idea to check how dirty your spark plugs are, and clean if necessary.

Depending on the age of the saw, if it's 35 years old or more, you may have to put less 2-cycle oil into your mix. The ratio has changed for all 2 cycle engines if they're approximately 35 years or older. Instead of 30 to 1 it's now 50 to 1.

I want to clean out my generator that has been sitting in my garage for almost 2 years, it has gas in it and it has been fired up only once since I bought it. Can anyone help.


First, I would drain out the old gas and put in freah and try it. If it doesn't start, try squirting gas into the carb and try again. Sometimes it will clear out the old gas a run. If not, the carb will have to be removed and throughly cleaned. The MOST important thing to remember about a generator, since they usually don't get used too often, is to ALWAYS keep FUEL STABILIZER in the gas.

Just won't start


check the spark plug after a failed attempt to start. If dry, then no fuel is entering engine.
Did you leave old fuel in carb? if so, your carb probably is dirty: old gasoline deposits varnish, gum, and you will need to dissassemble carb and clean it.
