Why does my Mantis tiller die at full throttle?
Because your engine needs more fuel to run at full throttle than to idle, if not enough fuel is in the engine it may cause your cultivator to idle normally, but then die when you run it at full throttle. If the fuel filter is clogged, it will not allow the correct amount of fuel into the engine.
What happens if you mow with the choke on?
Lawn Mower: Only Runs With The Choke On. If your lawnmower will start and run with the choke on but dies when the choke is turned off, it may have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine.
Why does my tiller only run on choke?
If your lawn mower only runs with the choke on, check the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine. There are several passages in the carburetor that allow fuel to enter the air stream depending how the throttle is set.
Why does my tiller keep shutting off?
You could have a clogged fuel cap, which can prevent air from entering the gas tank. Loosen the gas cap a little and start the tiller again. If it starts and stays running, try cleaning or replacing the gas cap. A clogged carburetor could also be the problem.
What to do if your ATV bogs under throttle?
As mentioned above, a dirty air filter is one of the primary reasons for a bogging engine. To fix the issue, check if your engine air filter is clogged or dirty. To ascertain this, check for a grey coating on the screen. Try cleaning out the air filter and check whether the problem goes away or not.
When to turn off choke on 2 stroke engine?
There is a simple solution for this one, but it’s an easy one to forget. Turning the choke on is important for starting a cold engine, but it should be turned off once the engine is warm enough to stay running. The choke creates a richer air/fuel mixture to be able to idle on first start up.
Why does my bike bog from quick throttle openings?
We’ll look at poor jetting in a minute, but let’s look at the other reasons why your bike bogs from quick throttle openings. An accelerator pump is simply a device (usually mechanical) on a 4 stroke carb that shoots an extra amount of fuel at low RPM throttle openings.
What happens when you turn the choke on for a carburetor?
When you turn the choke on for a carburetor, it is creating a rich condition. This makes the bike easier to start, by increasing the amount of fuel present in the air/fuel mixture. When an engine is cold, it needs a little richer mixture in order to get up to operating temperature.
What causes bogs when I open the throttle fast?
Turning this screw clockwise will rich the mixture and worsen the bog. If you find that you go more than 2.5 turns out on the air screw you need a leaner pilot, and if you’re less than 1 turn from closed you need a richer pilot.

Why does my dirt bike only run on choke?
You won’t see one of these on a dirt bike because the choke circuit actually just adds more fuel to the mixture with the same amount of airflow. So, a far too lean air/fuel mixture is why your bike only runs with the choke on.
