Question about Poulan 25cc 2-Cycle Gas Powered String Trimmer with Curved Shaft #P1500
The trimmer starts like a dream but only runs with the choke on and no throttle. After a while (10 mins) it stops altogether and won't start again. If I rev it up after starting it will get the rpms, but then dies. Idling with the choke on will work, but the rpms are too slow for any meaningful weed eating to get done. The chain saw attachment is worthless because of this lack of power.
Sounds like the carb needs to be removed and cleaned. It the chunk of metal that has the fuel line going to it on top of the engine.
Use a phillip screwdriver and possible a small ratchet to break it down and clean it thuroghly with gasoline.
After you get it back together and have cleaned it up as much as possible, crack her up with full choke again. this time though, allow it to run and barely ramp up the rpms enough to give it a little lug. When the engine seems to begin losing power, (these adjustments should be as small as possible until you get her running smooth) dial the choke back just enough to ramp up the rpms. This will probably take a few tries, but most definately should work in your case.
Once the trimmer is running smooth with the choke off you will be good to go.
Many times our trimmers and other 2cycle engines dont get the proper attention to keep them running up to par. Take the time to consider the unique properties of your tools to determine any possible future repair. Anytime you have and engine that burns a home mixed fuel there will be the risk of trash in the fuel system
GOOD LUCK AND PLS RATE THIS POST!!!! :D

In North Carolina because of the Ethanol in the gas, I have problems. To get my machines to run efficiently I have to use the best grade or find a Gas Station like Valero that don't use ethbanol.
