Well, only 2 things, is it getting gas?? Is is getting spark?? Squirt some gas down the cylinder and see if it will fire. Yes? No? If it fires, but won't run, the carb is messed up, or the fuel is not going to the carb. Then check the spark with the plug resting on metal and connected to its wire. If you have no spark, that is what you have to chase down. Sometimes these things sit and the contacts on the alternator rust over, (iron) and don't develop any juice, they have to be cleaned, the coil could be shot. The Carb might have been cleaned, but is it clean? Those jets are finicky. And gas that sits turns into rock. Check it out. Hope this helps.

Check for spark at spark plugs then check fuel and fuel filter .

Troubleshooting a small Petrol engine that won't start requires a series of short tests and the process of elimination.
Understanding the principles of how a small engine operates is helpful but not necessary.
Proper disposal of hazardous liquids will be required.
The knowledge gained in the performance of this procedure can be applied to many different types and sizes of internal combustion engines.
The average weekend mechanic can complete the process in about an hour.
Put on the safety glasses.
Remove the gas cap and check that there is gas in the fuel tank.
Look at the inline gas cutoff valve located below the gas tank on the fuel line and make sure it is in the on position, with the knob turned straight in line with the fuel line.
Look at the spark plug and check that the wire is securely plugged onto the plug.
Try to turn the spark plug by hand and make sure it is screwed firmly into the hole.
Look at the ground strap by the spark plug and make sure it is not touching the spark plug.
Look at the kill switch located by the controls and make sure it is in the run position.


Remove the air filter by unsnapping its box-like cover or removing the wing nut that holds it onto the carburetor.
Lift the air filter out of the holder and set it aside.
Spray a shot of starting fluid from the aerosol can into the empty air filter area of the carburetor and try to start the engine.
Let the engine run about 30 seconds or until it dies.

Eliminate the electrical system as the cause of the problem if the engine started right up, ran a few moments, and quit.
Remove the gas line from the carburetor by loosening its hose clamp with the screwdriver kit.
Hold the fuel line over the clear glass container and let some gas run into it.
Look at the gas, checking for water and impurities.

Drain the gas tank if the gas looked impure.
Remove the gas filter from the fuel line by loosening its hose clamps with the screwdriver kit.
Replace the gas filter with a new one if the gas did not run into the glass at a rapid pace.
Reinstall the gas line and gas filter.
Fill the gas tank with new gas.

Find a small drain bolt located on the very bottom middle of the carburetor.
Place a small container that gas won't melt under it and remove it with the wrench kit.
Let the old gas drain out of the bottom until the new gas starts to flow out. Screw the drain bolt back into the bottom of the carburetor.

Clean up any spilled gas off the motor and elsewhere with the shop rag.
Place the rag in the metal bucket a safe distance from the work area.
Clean the air filter with warm, soapy water if it is the spongy type, or replace it with a new one.
Install the air filter. Start the engine.

Unplug the spark plug wire from the spark plug if the engine did not start.
Hold the insulated part of the spark plug wire with one hand and place the bare part about 1/4 inch away from the top of the spark plug.

Try to start the engine and watch for a spark between the wire and the plug. Replace the spark plug wire with a new one if it shocked you through the insulation.
Remove the spark plug using the spark plug wrench and replace it with a new one if there was a spark.
Try to start the engine. Let the engine run until it performs smoothly.

Do not do anything else if there was no spark, as the trouble is inside the internal workings of the engine and requires professional repair and tools.

My ryobi x430 will not start. Replace spark plug and still won't start


hello sir, my machine will only start when pumping primmer bulb or squirting fluid in the carburetor than stops. the fuel line has broken off, in most small carburetors this is a ongoing problem.old fuel will crystallize when left in tank for a long time.plugging up ports, fuel lines, small screen in carburetor.fuel lines will dissolve clogging carb.this is why it will run when the choke is on creating a vaccum to where there is fuel forced in the carb to rum,also the gas will evoporate leaving the oil behind clogging up carb.the thing to do is remove carb. and clean out,replaceing gaskets or fuel line if necessory.use carb cleaner to clean out carb.make sure to make note where fuel line go.the fuel filter broke off of fuel line letting debris get in carb plugging it up.the muffler is known to clog up a lot on these machines where thay want run. the compression should be 60 to 120 lbs any thing below 60 is junk. when adjusting the carb screws turn in all the way than turnout 1 1/4 turns turn in slow untail machine runs also you need to check for spark by removing plug and grounding aginst engine to chech spark, ok.a new spark plug would be a good ideal too , if you are going to make these repairs use new fuel line and filter,hope this helps,any comments welcome,thank you, 11

Troy Bilt self propelled lawmower won't stay on. It's been fine this year, today all I did was add gas and added the mulch shoot. I turned it on, it was fine. Started mowing, got halfway across...


The trouble you are experiencing could result from several different things. First, check the oil when the engine is cold and completely settled in the sump. You do not want to overfill the engine with oil. If the oil is on the full line (not above it),then the low oil sensor is not shutting off your engine. The oil level should be exactly on the full line-not above or below. Second, remove the spark plug and clean it with a small wire brush or sandpaper. If you are unsure about how to clean the spark plug, replace it with a new one. If both of these procedures have been performed and the mower still doesn't run correctly, the problem is almost certainly with the fuel supply, fuel quality and/or carburetor.

Engine on powerwasher starts but quits running after approx 10 seconds. Engine oil changed, oil is full & tried choke in various positions. Also has fresh fuel in tank. What else can I do


try cleaning the carb that ethanol plays havoc on these small engines if it is not a premix oil and gas unit add a little 2 cycle engine oil to the gas will keep the carbon builup to a minimum not to much it will gunk up your spark plug take the carb apart and clean it with carb cleaner or deisellet dry check your spark plug make sure it is clean and ok that is where I would start

Bought unit new last summer. Used it once last summer and once this year. It started fine both times. Today, it will not crank. I have replaced the spark plug, checked the air filter (it is clean), gas...


Unable to crank? Do you mean unable to start?

If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor.
To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.

Starting the engine:
Take off air filter and spray WD-40 directly into carburetor.
Start engine, engine should fire on the WD-40 accelerant.
If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going.
If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad.
Try fresh gasoline.
Do not turn small engine on side or upside down or oil will get into carburetor.

Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose.
If gas is flowing to carburetor, then carburetor is gummed up.
Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor

If engine will not fire on WD-40
If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged
Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily?
Check spark
Remove spark plug
Put spark wire back on spark plug
Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug
Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity
Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal
If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement

ENGINE STARTS FINE BUT ALMOST IMMEDIATELY DIES, CLEAN PLUG & NEW GAS APPEARS THAT IT'S NOT GETTING ANY GAS BUT CHECKS OUT OK


You may have some condensation trapped in your carburator. I don't know about your make and model, but small engine 101, gas and spark ought to make something happen. If you have good gas and good spark, there's something denying the gas access to the spark. Condensation is a #1 culprit.
Hope this helps... Good luck!

Car wont start


The problems could be:
1- Check your spark plug. -see any fire come out- " dirty or clean"
2- check the crankshaft sensor - ( you can clean it)
3- check to see the gas go to the fuel injector/caburator line
* If your car use caburator- you may have gas over flood in the cabu. like your father said. IF there is no gas flood- try to spay the cabuator start bottle that you can buy any where in car part store.
I have all three different problems above since I am driven. Good luck.

Yard machine tiller won't stay started!


There is a small diaphram on the side of the carb that simply wears out. It's rubber coated mesh and the rubber coating breaks down and it stops pumping fuel into the carb. Sometimes you can run with the choke on partially, but it will burn 10 times the amount of fuel and cause more damage to the engine itself. I think it's about a $10.00 part.
