Hi kasch 97...

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:
Mark each piece with a awl, or some kind of 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 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 condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one.
Make sure you are using fresh fuel.
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 rebuilt that should solve your problem.

Clean the brass bolt very well that holds the bowl on the carb. Pay very close attention as their are some very small holes in the smooth part of the bolt near the top, as well as the bottom. Use NO metal objects to clean this bolt.It is the main jet of the carburetor also. Once cleaned properly, your fuel flow into carburetor and engine should be restored.

Hi Tim
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:

Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.

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.

How do i clean the carburetor?


go to auto store and buy a can of carburetor cleaner. not in spray can but a liquid that you can soak the carb. in. Take the carb off and place in a coffee can with the cleaner let it soak overnight. do not remove the set screws unless you have the proper settings to put them back as they were. Also in the bottom of the carb you will see a small pin hole clean it out with a stick pin. You can take off the bottom of the carb where the float is to clean it as well just be careful not to loose any parts. After cleaning it put it back together.

you more than likely sucked crap into the carburetor jet. Drop the Carburetor Bowl and check the Jet for an obstruction

Model 54 m runs only on choke for a few then dies


Change out old fuel,change in line fuel filter if there is one - you may have one in the tank, remove and clean carburetor passages - be careful with the gaskets - if you do not tear them they can be used again - make sure screws are tight. You might have to make adjustments to your mixture screws if applicable on the carburetor,clean air filter and plug. Recommend the new E3 spark plugs.

My 3 year old Yard Machine 139cc started (choke out), but then began running excessively fast after pushing the choke back in. A few weeks later, it still started (choke out) but now ran very fast even...


Check the carburetor see if all the bolts are tight.check the cylinder head gasket take off plug wire make sure it is away from plug so it wont start. Pull start rope can you hear air being pulled into the engine? if so the head gasket has ruptured or head bolts came lose. Ensure all parts are tight. Ensure fuel lines are not clogged. Check fuel level.

Sounds like you will need to clean your carburetor.
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.

That way when you go to put the jets back in, you know how many turns they were in/out.
