Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please rate me, Thanks
Good Luck, I hope this helped

Crafsman 25cc weedwacker won't stay running


You probably have a bad hose or a bad hose connection that is sucking mostly air instead of delivering full fuel to the carburetor!

Husqvarna 128LD backfires through carb when increasing throttle.


Possibly an ignition module issue, on the advance settings. It could be sparking before the piston closes the fuel port from the carb

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.

Wont stay running, replaced spark plug and air filter, starts but wont stay running


Try mixing fresh gas mixture, any fuel over 30 days old is gone bad, this may help. Or the carburetor may need rebuilding, or the exhaust screen on the muffler is clogged up. Remember before taking anything apart use either PB blaster or Deep Creep on the bolts before loosening them.

Trimmer won't stay running without starter fluid


drain any old gas/fuel mixture out of unit.
purchase new gas and mix with oil as recommended for your engine.
clean the air filter on the unit.
pull the spark plug and clean with carb spray and reinstall...

you also may need to remove the carb and clean any jets with carb spray... old gas can turn into a shellac'ish type goo and foul up the works...
I recommend draining all fuel after usage...

Will not start normally


Your carbeurator has crud in it from leaving gas in it over the winter.
You may be able to clean it using a carbeurator cleaner spray which you spray into the air intake after you remove the air filter, OR by using a gas additive such as seafoam which will clean the carb. as it runs. If you have any old gas in the tank of your weedwacker, discard it. Same goes for your portable gas tank. Gas deteriorates over the winter.
