Possibly the spark plug, idle screw is set too low, air getting into the fuel line. Does it run at higher speeds but kills when trigger is released?

My poulan 4018wt has been a hard starter from new. It started to act up out of the blue and started shutting off halfway into the cut and didn't always want to idle right. So I changed the spark plug,


I'd say the most probable culprit is the fuel.... I'd first try dumping the tank out, mixing fresh gas with the addition of a fuel stabilizer and start the saw. It'll quickly vent any old gas in the line and should begin to run fine with the new mix. If not, consider returning it to the service center for adjustment.

Never use gas that has sit on a shelf for months at a time as it becomes 'stale' (for lack of a proper term). Todays 'formulated fuel' can be a cause a bit of a problem for some small engines. Anytime you refuel, shake the can to remix prior to filling.

The oxygenated nature of the blended gas sometimes causes the chain saws to run a little 'lean'...meaning too much air to fuel ratio which could be a portion of your problem. A lean running saw will run hot and scoring of the piston or cylinder wall is possible. Some finely tuned professional saws need carb adjustments between the summer blend and the winter blend gas.

When you cleaned the carb did you put a new kit in? Did you blow out the passageways? Sounds like a bad diaphram...

Won't idle, cranks and runs fine as long as trigger is depressed


Could be just a carb adjustment required, the L screw on the carb will richen up the mixture, if increaseing the the idle screw does not help, try extra 1/4 turn out on the L screw, make sure the air filter is clean before makeing any adjustments.

Will not run at low idle


Fresh gas.new fuel filter and fuel lines and clean carb and screen and make sure your diaphrams are good, preset your jets 1-1/2 and run and fine tune once you get it going, also check your exhaust port and screen for being plugged

Poulan 446t Will start, won't continue to


The diaphragm in the carb is likely ruined from the gas gelling onto it. This will put pinholes in it and then it won't work properly. Pick up a carb kit and rebuild it (if parts available) and then you should be good to go. If you can't rebuild the carb, a replacement will run you 30 bucks or more.

I have a 14" Woodshark Poulan chainsaw. I put in


Poulan Chainsaws are pretty well all powered by two stroke engines. My best guess is that you have the fuel mixture incorrect (it should be a 1:40 ratio of oil to gas). if the fuel mixture is not the problem then your choke is messed up. If you haven't tried already try and find the sweet spot in the choke where it will run.

I have a poulan p3314 chainsaw. It has been sitting up for a while. When I started it, I could not get it to run beyond an idle. Every time I squeezed the gas, it quit. Finally, it quit and refused to...


The ful line actualy disloved and the problem is inside the carburtator there is a valve that lets fuel into the fuel bowl and also shuts it off when its full the floats control it so its always opening and closeing that is stuck closed from the melted fuel line you need to clean the entire carburator out the neddle valve may have a rubber tip at the seal point so take care not to damage it ware it makes the seal but its not hard to do anyone with some common sence and a little mechanical abilitly can do them selves

Idles fast, won't cut wood, stalls under load


Clean the fuel filter, air cleaner and muffler if clogged. Check all fuel lines for condition--replace any with original rubber lines--not plastic. The carburetor sounds like it could use a thorough cleaning and re-kit. It's somewhat common for saws to leak some bar oil over a long period. Good luck!

My poulan riding mower goes dead whether cutting or idling..already checked the gas tank,lines,filter,and carb for trash..all clean...what could be the problem?


Could be bad ignition system. Check for spark when it quits using a new spark plug. Why do you suspect the fuel system? Does the engine quit suddenly or sputter to a stop? Does the engine have to get hot before it will quit? Sudden stop is usually ignition loss whereas sputtering could be either fuel or spark loss. Safety switches--'rider present'--could possibly be a problem and cause ignition loss.
