Mower was tipped upside down and now won't start

I have replaced the spark plug and the air filter, and have used carbuerator cleaner. The engine will fire but won't stay running. I think this is a 6.75 horsepower briggs and stratton engine. Can anyone help?

First check to see if you have enough oil. If you do does the engine smoke? If it does, continue to start and let it run until it stops. If the time it runs keeps extending, keep doing it. You are trying to burn out the oil that leaked in to the cylinder when it tipped. If that doesnt work, write..Good Luck...Lee

Echo PB 251 won't run. replaced plug, gas, fuel filter, air filter. took carb a part, and cleaned with carb cleaner, used the compressed cleaner to clean out venturis/ports.


Wow! with all you have done it should run. Be sure the switch is on but if you are getting spark, it should be on. I would take it to the echo place for service.

Craftsman 675 series 190 cc lawn mower Wont start


Take air cleaner off. Shoot some spray carburetor cleaner in the carburetor and try to start Try this a few times to see if the engine will fire.. If it fires or starts then there is a fuel delivery problem. Could be a dirty fuel filter, bad (stale) gas, a dirty carburetor. If it does not start with the carb cleaner, check the spark plug. It may be fouled. Check for spark - take plug out of head. with the plug attached to plug wire, hold plug with a pair of insulated pliers, and touch outside of plug where the threads are to the engine, while some one pulls on the start cord. You should get a bluish spark. If you get a weak spark use a new plug and try again. There should be a bluish spark. Make sure you hold the plug against the engine making good contact. If no spark at all, could a bad magneto.

Getting back to the carburetor. If you think the gas in the tank is stale, drain it out and put fresh gas in the tank. Change the gas filter.
The arburator may be cleaned by pouring a 1/2 can of fuel system cleaner in the gas tank and spraying the spray cleaner down the carburetor throat.

If it turns, then the battery is OK. Either spark plugs are not firing in proper order (wrong firing order), no power to spark plugs, or no fuel because of fuel restrictions (dirty fuel filter). Inspect the air filter to ascertain its not clogged air. If you smell gas, then you saturated the spark plugs, which is why it refuses to run.
Let it sit for half hour to let spark plugs dry. Inspect to ascertain its not dirty spark plugs, which will also prevent engine from running. After ascertaining its proper firing order, spark plugs are clean, and there's power to distributor cap, ascertain there's fuel in fuel lines by squirting half second (short squirt) of starting fluid into air filter. Close the air filter housing to trap flammable starting fluid gas. Turn engine without giving throttle. Let starting fluid be ignited by spark plugs. If it won't start, then spark plugs are not firing to ignite starting fluid gas. If it starts briefly, but won't run when you give throttle, but catches when a 2nd person squirts more starting fluid into air filter just before engine stalls, then its a fuel restriction issue or no fuel in fuel lines.

2002 ford escort zx2 replaced fuel filter, air filter, plugs, and MAS...why won't it stay running?


it could be down to your spark plug leads take the leads out one by one and get somebody to hold the lead to the engine [to earth it] NOT WITH YOUR HAND with something thats not conductive like something plastic then try starting the engine to see if a spark jumps from the lead and repeat this please dont do this with your hand its very dangerous enouf voltage to knock you out!

Why won't my truck stay running when I'm not


Try cleaning your throttle body. Over time on high mileage vehicles, the throttle body butterfly valve will gunk up with sludge, and dirt. This will prevent air from entering the intake manifold while the engine is idling, causing low idle/stalling. A can of throttle body/carb cleaner will do the job. First, remove the intake tube to get to the butterfly valve. Spray a small amount of throttle body cleaner directly into the intake, and wipe any excess fluid with a cloth. Also, inspect your air filter. I hope this helps

My pressure washer doesnt seem to run properly. i have changed the fuel,air filter,spark plug and the oil. It will start but runs poorly.


Ok the first thing you need to check is if the spark is fireing. To do this you need to remove the plug plug it into the spark plug cap hold it on the cylinder head pull the engine over it will pull easy and see if you have a blueish spark jumping the gap on the plug . If you do its not an electrical prolbem . Then put the plug back and plug the ignition wire back and remove the air cleaner see if it will start then .witch the choke on . If it still won't start try pouring a small amount of fuel derictly into the carbuator if it runs for any time at all or even starts to fire then its a fuel issue eighter bad fuel or clogged filter or carbuator needs to be cleaned. You can even put a small amuont of fuel right into the spark plug hole then put the plug back in and it should start You need spark fuel and air for any engine to run if you have all three its automatic it will at least fire Good luckwith this

My troy built 2200 pressure washer was running fine but then shut off instantly I then noticed it had low oil I filled it but now it won't start


9224467.jpg
Pressure washer takes oil in two places:
Pump oil is 20-30 weight SAE non detergent and comes half way up/ do not fill more than 1/2 way
Engine oil is 10W30 and comes half way up dip stick
IF you overfilled the oil >>> DO NOT turn power washer on it's side or upside down to drain oil >>> because engine oil will fill carburetor

When engine won't start
We pull off air filter so we have direct access to carburetor
Spray WD-40 into carburetor while starting
The engine will fire on the WD-40

You can keep spraying WD-40 into carburetor to keep engine running while moving choke to see if engine will run on it's own
Squeeze gun trigger so water comes out gun and pump pressure doesn't stop engine

If engine will not fire on WD-40
Spark is suspect
Your spark plug gets power from ignition coil
If coil is bad you get no spark > and coil needs needs replacement
Take out spark plug, clean it with WD-40 and use a bit of sandpaper in the spark gap
Put spark wire back on plug
Touch threads of spark plug to metal part of engine > pull cord and look for sparking between spark plug and engine
If you do NOT have any sparking, then coil is bad
If you HAVE spark, then your spark plug needs cleaning or replacement

If engine fires on WD-40 but will not keep running
Then either fuel or carburetor are suspect
Loosen hex nut on fuel filter located below gas tank >> if fuel flows, then re-tighten hex
Next, pull off rubber hose connected to carburetor to see if fuel flows to carburetor
If fuel is flowing to carburetor, then the carburetor is suspect.
Small engine repair shop will have carburetor cleaners

Check exhaust
There is a screen over exhaust
Make sure it is clean of carbon build-up > Use WD-40

Change air filter

Poulan 6.75 Lawn mower will not start


Remove spark plug, clean and dry. Replace plug. Remove air filter. Spray WD-40 into carb opening; one second blast. Turn over engine, (pull handle). Engine should start briefly and run for 3 seconds.  If not, you are not getting spark to spark plug. If engine starts, you have a dirty carb and you can buy a rebuild kit from manufacture.

Will crank but won't fire


To run, the engine needs fuel/air mix, compression, and a spark. See if you can narrow your problem down to one of these. Remove the plug, then connect the plug wire and set (or carefully hold) the base of the plug against the cylinder head. Crank the engine and see if there is a spark. If not, the problem is in the ignition system.
If you see a spark, replace the spark plug. Remove the air filter and pour about a tablespoon of gasoline down the carburetor throat. Crank the engine, being careful to stay away from the carburetor in case it backfires. If the engine fires and runs, then it probably is not getting gas (fuel system problem), or not getting enough gas (carburetor or choke problem).
Compression problems are less common, unless the engine has been abused somehow. You can check for compression with a compression gage. Remove the spark plug, install the compression gage in the spark plug hole, then crank the engine with the throttle open and the choke off. If you get at least 60 or 70 psi when you do this test, the compression is probably not the problem.
