    You could pull the air silencer off to see if any carb is flooding. It's OK to run it on a hose or at an idle with the box off, just don't run it under a load with the box off.

Fuel primer


The primer bulb fills the bowl of the carburetor on initial start-up. Most primer bulbs are depressed 4-6 times. Set the choke at half and either pull the starter cord four times. If it doesn't start, re-prime and take the choke off.

Have huqvarna 350 it will not prime the bulb is good it check it . how can i check to see if it the carb or some other part of the fuel transfer system? when i pump i see the fuel from the carb being...


The bulb pulls fuel from the carb, if there is no fuel in the carb then it will not prime, reasons for no fuel in the carb is, blocked fuel filter in the tank, fuel hose trapped or split, internal filter in the carb, under the pump diaphram ( alloy cover on the carb held with a single screw ) blocked, you can test the primer, pull the two pipes off, the longer tube on the back of the primer should create a pressure when you press the bulb, the shorter connection should create a suction when you let go of the bulb.The suction side should be connected to the carb.

Diagram of fuel lines from tank to primer to carb and back to tank for a poulan 2050 chainsaw.


clip_image002.gifFuel components are onthe "Engine Assembly" & "Handle, Chassis, & BarAssembly" detail pages.
Replacement fuel lines can be found at yourlocal chainsaw seller/mechanic. They are different diameters.

Fuel Line Replacement
  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.

Primer button will not fill up


The primer bulb pulls fuel from the carb, into the bulb, and pushes it back to the tank. If the bulb does not fill there will be a number of reasons why, firstly if the saw is new, there will be oil in the carb from the starting prosess at the factory, the saw will start without fuel in the bulb, but will take many more pulls to get it going, once the saw starts and runs for a few minutes the oil in the carb will clear, and the bulb will fill normally when depressed, if your arm is not up to cranking the engine many times, remove the top cover, remove the air filter, dribble some fresh fuel/oil mix down the filter elbow, the saw will start after a few pulls. If the saw is a used machine the problem may well be a blocked fuel filter in the tank.

I have an echo C8 345 that will not run more than 5 secs. when you push the primer bulb and fill the carb, it will run until that is used up and quit. i took the fuel line off at the carb and gas runs out...


If pushing the bulb feeds fuel to the carburetor it isn't conneced properly.

  1. The filtered hose from the fuel tank connects directly to the carburetor input connection.
  2. The output line from the carburetor connects to the suction side of the primer bulb (once bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb reinflates).
  3. The pressure side of the primer returns any excess fuel to the tank as it is depressed.

drain fuel tank. keep depressing the primer bulb until it is clear. drain tank again. remove carb cover and disconnect lines one at a time. keep depressing primer bulb to get rid of excess gas. remove spark plug an turn engine in a position that the spark plug inlet is facing the floor, pull starter rope a few times to get rid of gas in the engine chamber.

My Poulan Pro weed trimmer SM132 does not run. I replaced the primer bulb and spark plug and it ran fine for 10 minutes. Now it will only start with the choke on and dies immediately. It will not start...


The primer does require two lines attached as it is a Walbro style primer. All four SM132 models uses the WT628 Carb. Since the trimmer ran 10 minutes then you have got all the lines connected right. Mostly you got trash in your carb or it simply needs rebuilding as the diaphragm may have pin hole in it or the check valves are worn out. Depending on the age and use of your unit you may also have a sticking piston ring.
