My trimmer starts but after warming up stops and wont start again
I have a McCulloch trimmer that when it starts and warm up (5 to 7 minutes) it stop and wont start again. You leave it to rest for a day or two and the same thing occurs.

It is possible for the gas tank vent to plug. To test for this open the gas gap after it stalls. Listen for the vacuum to release as you first crack the cap. If you here the sound it is a certain tell that the tank as the fuel is consumed by the blower is creating a vacuum which intern prohibits the fuel from entering the carburetor.
After releasing the vacuum the engine should start and run for several more minutes before repeating the cycle. Each blower has its own solution to allow for venting while minimizing fuel leakage,
For your particular machine a specific part is required if you determine that a plugged vent is the root cause.
It is possible that the engine is overheating. The root cause would be debris caught in the air passages that allow air to flow around the air cooled cylinder. If the machine gets very hot the heat will travel up past the heat dam gasket and baffle reaching the carburetor. This excessive heat would vapor lock the carburetor stopping the feeding of the fuel into the engine.
Close examination to ensure that all air passages are clear of leaves and debris is required. An air hose/vacuum may be helpful if you determine that the passages are blocked.
The third possibility would be a spark coil that fails as the engine gets warm. A qualified technician may be required to confirm this failure.
Could be several different things. Carry a can of carb cleaner with you and run it till it quits. Then remove the air box and try to start again, try using the choke, try a squirt of carb cleaner in the carb ( not at the same time ). If it tries to run then its a fuel issue or an air leak. If it wont run then its got low compression or a bad ignition.
Typically: 1. Press primer button 6-7 times until you see fuel flowing 2. Engage the choke lever to full choke /--/ pull cord 3-5 times until engine begins to start 3. Move choke lever to 1/2 choke and pull cord 2-3 times until engine starts - - allow to warm up (about 30 seconds) and move choke lever to no choke / / / 4. If engine does not start, repeat 1-3 If engine does not start, repost with more detail. Thanks! :)
My suggestion is to return it. This is just a sign of future problems
you are likely to have in the future. Think about buying a better item
from a dealer that services what they sell. It is very much worth the
difference in price. More than likely the unit they sell you will last
5 times longer than what you buy in the home center. Think about it.
The servicing dealer does not want to have to repair everything they
sell 4 or 5 times a year so they will not sell you junk.
well take the spark plug out take some WD40 and give it a shot inside the unit, remember to keep the unit level when hitting the throttle and allowing it to warm up for a few minutes before use also make sure where your choke lever is. also when starting I start it on the ground like most manuals state and leave it idle on the ground for a minute before picking it up and then when I pick it up I make sure that the gas tank is tilted towards the ground so there is no room for air to get into the filter causing and disturbance while the unit is warming up.
