Sounds like fuel starvation, always start with simple things first, replace the fuel filter in the fuel tank, check the fuel hose up to the carb for signs of leaking.

SOURCE: Craftsman Chainsaw will not start

It's your ignition, which you can take that stuff apart on the left hand side of the saw under the recoil. I have 2 of these, & you can get the parts. Maybe its just the magneto gap adjustment, which is like a business card or newspaper width gap. I would check that first. Hope this helps you, Rick

SOURCE: Husqvarana Rancher 55 , how to clean the exhaust port

Cleaning the exhaust: on the saws I've worked with it was just to loosen two bolts at the front and then the exhaust is off the saw. Clean with brake cleaning fluid and blow with compressed air, let it dry before assembling. Don't forget to clean the fine mesh at the output side underneath the lid if present (i.e the spark arrestor).

Make sure to have your carb adjusted properly afterwards.

SOURCE: Husqvarna ranger 55 chainsaw starts but quits

I too have a rancher 55 and had what sounds like the same problem this week. It would start fine but run for only a few seconds at a time. I took it all apart today and found the problem - a cracked fuel line. In the places where I could see the hose it looked fine, but it wasn't until I removed the fuel tank that I found the crack...right where it exits the tank and then goes thru the housing above it. You don't need to remove the tank to replace the hose but it is easier that way. You do have to push it thru a grommet at the top of the tank. I read some other posts about checking the tank vent to see that it's not plugged up. Mine was ok so I knew it had to be something else. The vent is in a hole about the size of a pencil and is recessed about an inch into the tank on the upper right side. Its partially covered by a plastic cap that's part of the vibration damper, which can be removed to gain access to the vent. The vent tube can then be pushed out from inside the tank with the use of long needle nose pliers, but be gentle. I just loosened it then pushed it out with a finger. I put it all back together with a new hose and its running like new again!

Engine won't stay running - only will start with starting fluid.


VERY COMMON problem with gas engines.

I recommend starting all your gasoline using machine ever month or two. Let them run a few minutes. Same with cars/trucks.

Start you r car/truck every couple months and drive forward and backward several feet as well.

If you have a gas shutoff valve, turn it off and run engine till all gas is out of carb before storing.

Gas turns to a hard lacquer is sitting too long. remove air cleaner covers, Pour some real good (strong/thorough) carb cleaner in carb and leave sit over nite. If that doesn't work, do it another nite. If not working yet, you may have to take carb off and open it up. Be careful there are little tiny parts in there.

Will not start after warmed up and sits for 5-10 minutes


Check that the spark plug is not fouled

Check to make sure your mixing your fuel
correctly & not adding too much 2 cycle oil

Adjust the idle & high speed on the carb
when you first start it up cold

Gas can not be more than a month or two old
& has to be regular 87 octane

Runs but quits


Probably gummed up carb. If you don't want to try to rebuild the carb, then try adding a really good carb / fuel injector cleaner to the gas/oil mixture. don't forget to use a very small amount, then run the motor as fast as it will go for short periods of time to try and dissolve the gumming in the jets.

My poulan saw will only run for 30 seconds and then quits. It ran for about 30 minutes before developing this problem. Plug is dry with tan color. Air filter is clean.


Try a few simple things first, clean the air filter, remove and replace the filter inside the fuel tank on the end of the fuel hose,check the fuel hose up to the carb for cracks and leaks, fit a new spark plug.

Saw will start. runs a little sluggish at first. then it will smooth out and rev high and run strong for a few minutes then gets sluggish again and dies. will not start again for 5 to 7 minutes minimum....


Being springtime, I'm thinking you may have had your saw sitting all winter with last years gas in it. If so, you'll need to clean the carburator and spark plug real good, then put fresh gas in it. Always remember to run your saw out of gas before putting it away. Gas only stays fresh for a few weeks and will foul up your sparkplug as well as plug up the inside of your carb when it gets stale.

87 ford tempo gl car will start and run for a while but then it quits running. then try to crank it over and it will start but quit immediately and it will keep on doing that. when it cools down it will...


It could be a fuel supply problem, plugged fuel filter or faulty fuel pressure regulator. When you turn the key to the on position, you should hear the the fuel pump run for a couple of seconds. This will tell you that the fuel pump is getting power, but it could still be weak. There are other things that could be causing the problem, does the engine have spark after it stalls?Do the injectors function?What is missing from the equation? Engines require compression, fuel, spark and air to run. If it is a fuel supply issue, after it stalls, you should be able to spray carb cleaner (acts as fuel) into the throttle body to restart the engine and keep it running at an idle by feeding the right amount of carb spray.

HARD TO START. WILL ONLY RUN ABOUT 20 SECONDS.


Your carburetor needs cleaned. Disassemble and spray with carb. cleaner. TIP: Use a Den Tek Brush, (used for cleaning between teeth),to clean small portals in carb. check the small screen in carb. for debris. Reassemble and start. If it still doesn't run properly, buy a carb. kit and replace the small screen, needle valve, gasket(s), and diaphram. this should definitely do it.

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.
