Why does my small engine only run with the choke on, and not the pressing primer?

The engine's fuel air mixture system is out of adjustment if the engine requires the choking after initial engine warm up.This symptom of running can be experienced by both the manual choke system and manual primer system engines.

Do you need to choke the engine to keep running?Once the fuel is contaminated, the bad gas can cause filters and carburetors to become clogged as the rubber hoses and plastic parts begin to oxidize.It is likely time to clean the fuel lines and filters if your motor requires the choke to be engaged.

It can't draw enough fuel with bad diaphragm.If the engine only runs with the choke full on, it means you have a vacuum leak and it's too lean.Sometimes a back fire into the carburetor will blow a pressed-inBB out of a drilled passage way.

A mower engine stalls because of the loss of air flow to the engine caused by too tall or thick grass or a dirty air filter.When you try to mow on a lawn that's too big, you end up blocking the air filter and shutting off air to the engine.

There are 3 answers.The engine will not be damaged by it.It will use more fuel because it will run richer.Even if you did it for thousands of miles, you'd probably end up with more engine/exhaust deposits.

Only runs smooth on choke means there's a problem in the main jet or nozzle area.It can be cheaper and less drama to simply replace the carb on a specific mower.

You might have a problem with the valve.You may be able to pull gas into the car with the help of the choke.When you hold your hand over the car, you will get more suction.

A choke valve can be installed in an internal combustion engine.It's purpose is to enrich the fuel-air mixture while starting the engine.Fuel injection began to replace carburetors in automobiles.

The choke chokes the air supply into the engine so it gets more petrol.It's name.If it's cold you should start the bike with half or full choke.It's usually enough for most bikes after 30 seconds.

The amount of fuel in the cylinder is increased by the choke going into the engine through the carburetor.This increases the chances of fire in cold weather.A richer mix in warm weather is simply wasted fuel as unburnt fuel is expelled.

It is clear that your engine is being fed a lean mixture if your bike is running better with the Choke ON.Adding more fuel or restricting incoming air is what most carburetors do.Both methods produce the same results.

There is a chance that air is getting into the engine through a leak.This air can change the air in the engine and cause it to stall.

The choke plate is covering the throat.If you have a handle bar mount, the choke is off when the lever is facing you.The choke plate isn't covering the throat.

If your chainsaw only runs with the choke on, it's probably an issue with your engine.The engine will not run if the Carburetor is plugged.If the engine is plugged in, the choke will allow it to run.

There are symptoms of a bad or failing Carburetor.A reduced engine performance is a symptom of a bad or failing carburetor.There was black smoke from the exhaust.Black smoke coming from the exhaust is a symptom of a problematic carburetor.Either backfiring or overheating.It was hard to start.

The Automatic Choke Park can be used to shut off the engine.Put the hood in place.There is a lever on the left side of the car.The stopping arm and the throttle lever should be loosened.
