I can't get it to start. Don't think the gas is moving when I pump it to start it. When I push on the bulb, it doesn't appear to pick up fuel.


Is the primer bulb filling with fuel.? If not then you either have a hole in the primer bulb or a hole in the fuel line, you mat also have a blocked primer bulb base.

I cant get it to start. The primer bulb wont refill with gas


The bulb pulls fuel from the carb into the bulb and back to the tank, if the bulb does not fill it is because there is a fuel blockage, either in the fuel filter in the tank, or the screen in the carb itself.

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.

My Husqvarna 128LD primer bulb will not fill with gas


The primer bulb does not have to be full of fuel for the carburetor and trimmer to operate correctly. The actual function of the purge/primer bulb is to help pull fresh fuel into the carburetor while at the same time, push old fuel/air out of the carb and back to the fuel tank. You may have bad check valves in the primer base assembly but, the machine can even operate if the bulb is only even 1/2 full or so...Make sure the fuel is moving in only one direction during and after the bulb is pushed and released. If it's not....bad check valves. These valves are very small and fragile and easily damaged by strong solvents, high PSI compressed air...and carburetor bath type cleaners. You didn't state whether the machine will start, run, what have you. Repost if needed. Please vote on this solution.

The fuel primer does not fill and the engine does not start.


I would consider a clogged fuel line or a defective primer bulb. Replacement bulbs are available at numerous retail outlets that sell lawn care equipment. I take the old one with me for comparison purposes. You say that the engine will not start. Will it start if you apply fuel or starting fluid directly to the carburator? If the engine will run in that situation, then I would consider the primer bulb or a clog in the fuel system as the cause of the problem. Hope this helped and best wishes.

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.

Ryobi 790r i have changed the gas line and the primer bulb . the primer will mash in 1 good time and then gets very hard to mash in . i fully choke it and it will crank but only for 3 seconds until it...


You cannot flood the engine by pushing the primer bulb too much, unless the hoses are hooked up backwards. The primer does not push gas to the carb, it sucks gas through the carb and returns it to the tank. Top barb on primer is the hose coming from the return side of the carb and the bottom fitting is the hose going to the return fitting on the tank. Look inside tank, it is the one without the filter on it, just a flange with a hole in the center.

If you can see gas and air bubbles moving through the primer and into the tank the hoses are on correctly. If you see bubbles going in the correct direction and then reversing when you remove your finger from the bulb, then the check valves in the primer may be bad. Replace primer.

When you say the primer "gets hard to mash", do you mean it is hard to push in or is it very slow to refill and return to the home position? If it is hard to push in and the bulb is full of gas and the hoses are on correctly then there must be a plug in the line going to the tank or the vent in the gas cap is not working. If it does not return, then it is most likely a plugged filter, plugged line from the tank to the carb, plugged screen inside the carb or a stuck needle valve. The primer is creating a slight vacuum to pull the gas through the carb, which is what the carb does when the engine is running. If there is a full or partial restiction on the supply circuit neither the primer nor the carb can pull enough gas for the engine to run. May need to disassemble carb and clean out any varnish, gunk or plugged ports/jets. Use spray carb cleaner. May want to think about a diaphagm and gasket kit if you do it yourself. If you do not feel confident in taking apart the carb, then take to a repair shop.
