20 Most Recent Poulan 25cc 2-Cycle Gas Powered String Trimmer #P2500 Questions & Answers

On the trimmers when torqing head bolts down,I dont bother looking for torque specs (theres some people that will shoot me for saying this). I just snug them up and then give each one a one quarter turn tighten up. Its always worked for me.

The trimmer needs a carb adjustment, but the adjustment screws take a special tool only available to dealers. Go to poulan's website to find a service dealer near you.

Because of the new oils, you can run either 40:1 or 50:1 Make sure the oil is rated "FD" even better, run the pre-packed fuels they are FD rated oils and 93-95 octane fuel with no ethanol.

Sounds like the fuel filter is particularly plugged. Maybe you had a little trash in your gas, or a bit of it was in the tank from manufacturing. Hopefully changing or blowing out the filter will help. That's the first thing I'd check.

I have yet to find parts for these, not worth the effort, I would replace the unit and sell for parts if it was under $150, or make the gaskets yourself, take apart and clean. Mostly I see failures beyond economical repair.

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

ethanol gas is very bad for carburetors. if you don't used the trimmer very often, the gas will ruin the carburetor. That goes for any carbureted machinery

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

just bought a new Poulan 25cc 2cycle gas power weed eater . I can start it with the choke on but as soon as put on run it dies.

Try changing the fuel filter and if that dont do it there is a small screen inside the carb that usually plugs up carefully disassemble it and clean it out with a good brand of carb cleaner

if it is a fairly late model you will need a carburator adjusting tool.you can get them on ebay then set each screw at about two turns and fine tune from there

What about the carb diaphragm do you want to know?

Are you talking about the inner shaft or the outer covering? Need a little more information.

There's only one way it can go back together. Go to ereplacement parts.com and pull up a diagram. Just put in your Model number in the search bar.

I don't know who you are answering, but I can help you. You have to make sure you have spark at the plug first. Then we can go from there.
How did it act the last time it ran? Has it been sitting for a long time? Do you have fresh fuel? When you respond to me, put your answer in the comment box on this page.
