When your trimmer starts and runs on choke, it could be because the check valve in the gas cap is clogged. Start the trimmer and gently unscrew the gas cap halfway off. Turn the choke off and assess. If the engine is still running, that means the gas cap may be the culprit.
Why does my 2 stroke engine only run on choke?
If your engine only runs when it’s half choked, there’s a problem. When a two-stroke only runs on half choke it is usually the result of a dirty fuel cap, a leaking gasket, a clogged carburetor, or a gunky passageway. You can fix these problems by cleaning the carburetor, removing the fuel, and adding new gas.
Why does my trimmer dies when I give it gas?
One reason why one of these trimmers may die at full throttle is that too much oil is in the gas, which causes poor combustion. Improper operation, including overuse of the choke, can also be responsible. Poor combustion produces carbon deposits that foul the spark plug and exhaust port, making the problem worse.
Why won’t my Weedeater keep running?
Remember: If your weed trimmer starts but won’t keep running that’s usually a sign of either a poor fuel/air mix or an easy-to-replace filter having gotten clogged, all of which are easy fixes to perform at home.
What causes a small engine to only run on choke?
An engine that requires the choking ( partial or full ) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment. Both the manual choke system and the manual primer system engines may experience this similar symptom of running only when the fuel mixture is enriched.
Why does my engine only run with the choke on?
If a motorcycle or ATV only runs with the choke on, it’s because the richer “choke on” mixture is actually closer to the engine’s normal operating fuel mixture than the leaner “choke off” mixture. So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls.
Why does my 2 cycle engine stall when I give it gas?
One of the possible reasons why your two stroke engine is stalling when revved is because of a clogged filter. The fuel filter stops any debris or gunk that may be in the fuel tank from entering the carburetor and engine. If this filter gets clogged, then not enough fuel can be accessed by the engine for it to run.
Why does my trimmer bog down?
The most common causes of a weed eater dying when throttled are fuel issues, insufficient air intake, or problems with the exhaust. You should follow the path that the fuel travels to identify the issue.
Why does my trimmer keep turning off?
Air Circulation The engine draws air into the combustion chamber through the intake port, and if the air filter is dirty, combustion is partial and the trimmer will sputter and die. When the spark arrestor is clogged, the engine can’t get rid of its exhaust gases, and it won’t keep running.
Why does my strimmer cuts out when revved?
Check for corrosion, breakage, deposits or melted parts. If you notice any of these negative symptoms, it’s time to replace the plug. A filter maintains a clean airflow inside the engine and stops small particles to enter and damage its internal parts. So, an air filter might clog over time.
How do you clean a lawn mower carburetor?

Does a fuel injected engine have a choke?
the lack of lash keeps the valve from sealing and lowers cylinder compression and vacuum in the intake. it becomes more noticeable in fuel injected engines as the choke (enrichener) will mask this effect by wetting the intake valves. Carbureted engines that close up lash will generally just not start at some point.
What does a choke do on a carburetor?
A choke valve/cable is designed to restrict the flow of air in the carburettor of an engine. This helps enrich the fuel-air mixture, improving the ability to start an engine in low temperature conditions.
Why does my lawn mower run better with the choke on?
If your mower is running better when the choke is on, it means the mixture in the chamber is lean. Too much air is getting into the chamber, so when you “choke” the air intake, the mixture stabilizes, making the mower run better.
Why does my 2 stroke strimmer keep cutting out?
If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. Remove the air cleaner cap and filter, checking for any obstructions in the way that could block air flow, starving the engine of oxygen.
When I open the throttle the engine dies?
A clogged air filter will starve the engine of oxygen, causing the engine to die at full throttle. The engine may idle normally, but at higher RPMs it may not get enough fuel, causing the engine to stall. To inspect or replace the fuel filter, follow the fuel line from the tank to the carburetor and locate the filter.
Where is fuel filter on Stihl weedeater?
The gas filter is inside the fuel tank on the end of the incoming fuel line. When your Stihl becomes difficult to start or often stalls even with a full tank of fuel, chances are the fuel filter is dirty.
