Poulan trimmer wont idle

Carb not set correctly. Screw down idle an fast run screws an then reset. Sometimes fuel gets clogged an needs adjusting

My chainsaw was doing this.The carburetors on these small engines have a fuel inlet screen that clogs with tiny bits of debris.Remove the carb,and take the portion off that has the fuel line attached to it(if you're careful,you can reassemble it without needing a new gasket).The screen is about 5/16" in diameter.Spray some carb cleaner in there to clean the screen out.(this is mt best guess,because it sounds like a fuel starvation problem)

When I bought a new poulan gas trimmer, I had the same problem. Solution was to return it and get another one. They come with problems, even new. Just keep returning them until you get one that works correctly. Mine works great, but like I said, had to return it and get one that was right.

Your carburator is clogged.
1st make sure you have FRESH gas.
Empty and clean the fuel tank
Remove and disassemble the carburator and soak it in fresh gas for about 15 minutes to disolve any gunk.

Using a can of small carburator cleaner ( available at Lowes, Home Depot etc.) blow out all the ports.
reassemble and refuel with clean fresh gas
The little carbs clog easily

you're trimmer could have one of two problems, One, if it has a clutch on the engine,( the way you would tell is if it doesn't spin when it idles. it has a clutch) Two, your trimmer would spin all the time, they use round flexable cables stamped square on both ends, which fit into square sockets one at the engine one at the trimmer head, so you're problem is either a worn out clutch, or, the cable is broken, or, one maybe both sockets have become rounded out. I hope this helps you out. Bob

clean and repair carb, make sure the mounting gasket is ok. and does not have a vacuum leak.

May be time to get the carburetor rebuilt. Sounds like the diaphragms are not working properly to pump fuel. You may need some lubrication on the throttle cable too. A little lubrication on the throttle arm would not hurt.
Good Day.

poulan ppb 330 33cc trimmer .idles but no high speed power.
my solution was to remove postage size screen on muffler known as spark arrester and clean. runs great know !

First of all, YES. boggs is a word in my dictionary. Remove the muffler and carefully take it apart. Pay close attention as to how it comes apart because it is vary important it goes back the same way. you will probable find that it is clogged. If it is then remove the debree. If it isn't then you will have to adjust the fuel mixture screw. First start the trimmer, then let it run for a few minutes to warm up, then gently turn the screw a little bit at a time counter clockwise first, squeezing the throttle inbetween adjustments . If it starts to take off then fine tune it untile your happy. If it boggs worse then turn it clockwise.

But first check the muffler.

Good luck

Are you taking the choke off after it starts?
