Fails to stay running / primer bulb does not fill

I have changed the tank lines and primer lines to and from the motor. For some reason the primer bulb will not fill properly and when the trimmer starts it only runs for 5 or 6 seconds them dies. I though it might be a clogged line bu the lines are clean and have been replaced.

Double check that the fuel lines are routed properly. Another place to look for a potential problem is where the fuel line comes out of the tank. Make sure the hose is not pinched. The typical fuel line routing is the first line (the one with the fuel filter in the end of it) comes out of the tank and goes to the bottom fitting on the carburator. The second line comes out of the tank and goes to the bottom fitting on the primer bulb and the third line goes from top fitting on primer bulb to top fitting on carburator. Hope this helped and best wishes.

The primer bulb on my Husqvarna 235e chainsaw will not fill. Why?


Number of reasons for the primer not filling, But i'll go with this one as you say the tank is under pressure.

Faulty primer. The primer has a couple of one way valves in it, so it sucks up the fuel while expelling the air in the line. Id say that the valve in the primer has failed and instead of pumping up the fuel you're pumping air into the tank. The replacing the primer. part number 545 00 80-30

Why will the plastic primer area will not fill up?


One reason that the primer bulb will not will with fuel, besides having no fuel in the tank, can be that the two fuel lines have been reversed. If you pulled the fuel lines off for some reason then switch their positions and see if that makes a difference when you push the bulb. You should see fuel moving back into the fuel tank.

Should ther be air in primer bulb after blower is running


An air bubble may stay inside the primer bulb after starting the motor. But if you see foaming or churning fuel coming into the bulb you may have an air leak in your fuel line. This usually occurs inside the gas tank because the line becomes hardened from alcohol exposure and then the fuel clunk moving the line around causes a split near where the line passes through the tank body. Believe me....the break will get worse and one day you wont be able to keep the motor running. So now would be a good time to size up the fuel line and pick up replacements. You can swap the lines yourself with a little effort and you will save money too. Bonus!

Be safe and good luck!

I changed the primer bulb and now it's not getting


sounds like you hooked the lines up backwards, when you press the primer it is supposed to squirt gas into the tank on the return line cause what it does is draw fuel through the carb and back to the tank....filter line from tank goes to fuel pump side of carb and return line on carb goes to primer bulb then opposite line on bulb to tank...... so when you press bulb it draws fuel through filter in tank through carb and back to tank ! good luck! 2StrokeJim

My Ryobi start great but when I change it from start to run stays few seconds and died


  • Alow the engine to run for longer on the start setting before you switch to run
  • Ensure air filter is clean. Foam elements can be washed with hot water and detergent. Paper elements can be cleaned with compressed air blown from the inside of the filter but ideally should be replaced.
  • Check fuel lines aren't kinked or blocked restricting fuel flow.
  • Ensure fuel filter isn't dirty. This is probably located at the end of the fuel line in the tank.
  • The fuel lines may have become airlocked.This can happen if the tank is run dry. If the trimmer has a primer bulb, alternatively press it several times and then try to pull start the engine with choke on. Repeat this several times. The primer bulb should feel spongy and fill with fuel.Once the engine kicks, switch to run.

Primer bulb hook up


Two lines come from the tank--one with a filter that goes to the carburetor, another with no filter which goes to the output side of the primer bulb and passes pumped fuel back to the tank. Connect only the line with the filter on the end to the primer and pump it. If nothing happens, switch the line to the other port on the bulb and pump again. With fuel mix in the tank, one of these two ports should pull fuel into the bulb. When correct, put the filter-less line on the other port of the bulb. Remove the filtered line from the bulb and hook it to the upper fuel connection on the carburetor. Use another length of fuel line to connect the now open port of the bulb to the other port on the carburetor. If the connections on the carburetor are correct, fuel will fill the bulb after a few pumps. If nothing happens, reverse the two connections at the carburetor and try to pump again. You should see fuel enter the bulb with only the correct connections at the carburetor. Usually, these connections are unidentified and must be found by trial and error. This is also a good reason for replacing only one line at a time! When fuel pumps into the bulb, attempt to start--with luck, the engine will run. Once the engine runs normally, trim the line lengths so that you have no excess line, but don't have sharp bends in any line either--they will eventually kink! Hope this helps!

Vapor lock


The tank vent is a bronze plug inserted into the tank casting--the caps are not intended to vent. Check the fuel filter for plugging and the condition of the fuel lines and primer bulb. You should be able to fill the bulb with fuel after several pushes of the primer bulb. Have the fuel lines been changed? Hope this helps!

Primer bulb won't re-fill.


Not sure about your particular set-up, but there is usually two fuel lines running from the fuel tank. One goes to the carb and the other goes on a fitting on back of the primer bulb. The primer bulb will have a second fitting with a line going to carb. Sounds like either a clogged or leaking fuel line to me. Hope this helps and good luck.
