You need a new carb, plain and simple. If it runs when you pour it in, the engine and coil are good. It doesn't make any sense to rebuild a carb unless it's like a 2-300$ carb on a large machine. On a two-cycle chainsaw, it's maybe 40-60$ for a new carb, versus a 20-30$ kit, plus labor (yours or theirs) and it's STILL going into an old, worn carb.

SOURCE: Poulan #2550 farmhand saw, Put a new carburetor on

Try emptying the fuel tank, and with small flashlight inspect the fuel line and the sump pick-up screen inside the tank. You may be able to gently retrieve it with a stiff wire hook. See if the hose is cracked/broken of if the screen is clogged. If all is well, be sure there are no kinks in the entire fuel line. 
Hope this helps

61 fires up then dies,seems to be good spark and gettin fuel

If the saw has good compression and spark (check them with proper gauges) check the fuel lines and fuel filter. If this all checks out, then the issue is probably the carburetor itself.

Model # 358.797180, 200 mph. At first I thought problem was carburetor being gummed up due to being improperly winterized by previous owner. Replaced carb with new, did not fix problem. Also replaced fuel...

The primer is just a small pump that is supposed to pull fuel through the carburetor from the tank supply line/fuel filter. The filter is supposed to be connected into the longer line at the rear of the tank. This lines goes to the carburetor uppermost port and the lower port is tied to the inlet side of the primer pump. Remove the tank side line from the pump during the pump test to make sure that you are not pulling fuel into the pump from the exit line. Try pumping fuel at this point--if nothing happens, swap the port connection at the pump and try to pump again--when correct, it will fill the tank supply line first, then the exit line from the carburetor that goes to the pump and finally fill the bulb. If you don't get fuel with either connection, then you have a leaking fuel line somewhere as you have already replaced the carburetor. Most saws use a rubber fuel line, not clear plastic. Hope some of this helps!

After starting and operating the chainsaw for a short time, it dies and I can't get it started again. Suggestions?

Engines require 3 things. Spark, compression and fuel. And chainsaw need 2-cycle oil mixed with the gas.

Assuming you have the right oil-gas mixture and a fresh batch of gas, and you didn't leave old gas in the saw all summer long since last November.

-Take off the dirty air filter and see if saw starts without filter. Do not run without putting in new filter.
-Check exhaust port for mud dobber home or screen clogged with carbon and dirt
-See if saw fires up after squirting WD-40 directly into carburetor
-Check gas line >>> pull gas line loose and see if gas flows out of tank to carburetor
-Take out spark plug > put finger over spark hole and pull cord >> do you feel suction that says you got compression?
-Put spark wire back on spark plug >>> hold spark plug so threads touch bare metal part of spark plug hole >>> pull starter cord and see if spark shows between plug and saw >>> suggest you not hold metal part of spark plug while pulling cord [you'll understand why]
-If spark plug shows spark, then your saw has spark ... so put in new plug and start fresh.

If your saw has compression, spark, and fuel it should start unless carburetor is gummed up because gas was left in tank.
Here is the final trick. Start the saw while spraying WD-40 directly into carburetor and see if you can keep it going with the WD-40. This might take a helper. If this does not work, then carburetor is bad or gas line is clogged at carburetor. Time to take it to the shop.

PP3516 ran slow for a while then quit.

Recheck the spark--if the plug is wet, it should have at least popped several times. Try a new plug gapped at 0.020". Check the fuel filter, air filter, and muffler for plugging. Check the fuel lines for decay or other damage--if replacing any, use original rubber lines only, not plastic. Does the primer bulb fill with fuel after several pumps? Remove the carburetor, and clean it inside and out with spray carburetor cleaner. Look closely at the lower chamber diaphragm which should be pliable with no holes or other damage. There is a small filter screen within the main body that can get plugged with stale fuel. Check the components between the carburetor and cylinder for any damage. Go to: for a 12 page article on Walbro brand carburetor theory and troubleshooting which also applies to other carburetor brands as well. Hope some of this helps!

Starts fine runs good for 1-2 minutes then dies. starts up with several pulls or choke. then dies again. changed the sparkplug no differance. cleaned the airfilter same result. george from texas

Check the fuel filter and muffler for plugging. Check the fuel tank vent for plugging. Check the fuel lines for damage or decay. Check all of the carburetor fasteners for tightness including the mounting hardware for the carburetor to the cylinder. The carburetor does not appear to be pulling new fuel into itself after running on the initial prime. If the above hints don't help, you may have to service the carburetor. Check the gaskets and heat insulator block behind the carburetor for any obstruction/damage of the impulse passage which allows the carburetor to pump fuel. Hope this helps!

Lawn mower will not start

check gas tank with light is there dirt in tank? did you change fuel filter? is there spark at the spark plug? try a 2 second spurt of starting fluid in carburetor and crank does it fire?if it does then you most likely need to clean carburetor with carburetor cleaning spray, flush fuel lines with spray and swap fuel filter.

There is a possibility that the flywheel 'keys' have sheared thus causing the ignitions to fire at the wrong time. Do the plugs get wet after pulling the engines through a few times? If not, try spraying starting fluid in the plug holes, reinstall the plugs and attempt starting. If you get a pop or two, you have fuel problems. Check the fuel lines, primer pumps, and fuel tank filters. Make sure the primer pumps pull fuel FROM the carburetors, not from the tanks. Remove the lines at the pumps that go to the tanks and try to pump fuel out of the open pump ports. When the mufflers were off, did you inspect the cylinders and piston skirts for deep scoring or heavy wear? Do they both seem to have good compression when pulling through? This should cover most of the common problems. Hope this helps!

Do not know where to atatch fuel filter

The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best; components are listed but may be on different illustrations.!retrieve.pd?modelNumber=358350380+&pathTaken=partSearch

It is made by Poulan (PP4218????) The small hose in the tank must be long enough to reach all corners of the tank as the saw is moved, the filter fits on the end in the tank. The other end connects to the lowest(1) fitting on the carburetor. A second small hose goes from the upper(1) carburetor fitting to the primer. The large hose from the primer into the center of the tank, (not critical length) nothing on the end in the tank.
(1) leave the 2 carburetor connections long enough they can be swapped. My description is correct but not 100% certain on the 2 carburetor connections. If it starts after priming then quits swap the carburetor connections and retry.

A typical fuel system and a couple of suggestions follow:

Clean the air filter, spark arrestor and muffler; if the saw cannot exhale it cannot inhale. Use a fresh 40:1 fuel mix (1 gallon of premium fuel to 3.2 ounces of quality 2-cycle engine oil) or 50:1 (1 gallon of premium fuel to 2.6 ounces of quality 2-cycle engine oil).

Once done please post back with how it runs and carb connections. I will give you a carburetor adjustment procedure if you do.

My 288 husqvarna wont start

Check for spark with a clean spark plug. If ok, squirt some starting fluid in the plug hole and try to start the engine. If you get a few pops, then work on the fuel system. Check the fuel lines from the tank to the carburetor for kinks, brittleness, or cracks. If it has a primer button, check the button for cracks or hardness and inspect it's lines. Do you have fresh fuel mix in the tank? Make sure the air filter is clean and in good shape. Check the muffler for plugging. If the saw is fairly old, the carburetor may need a re-kit and cleaning. Good luck!

Toro TimeCutter z4200 will not start

First check to see if there is a fuel shutoff under the tank. On some models there is a fuel filter screen inside the tank where the fuel line connects to the tank. If niether of these work, R&R the carb.
