Do you have to choke engine to keep running?
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.
Should a motorcycle start without choke?
You should only need to choke the motor in colder weather to help add fuel on a cold startup. Fuel will condense on the cold metal parts of the intake track otherwise. Using the choke to raise RPMs to help it idle cold without needing extra fuel will just foul plugs.
What happens if we drive bike with choke on?
Generally, no permanent damage to the engine, but your spark plug , piston , valves will have higher carbon deposit, as also the exhaust pipe, which will need a cleanup earlier than otherwise required. With normal running, the excess carbon could get burnt off , avoiding the need to decarb manually.
What happens when choke is on?
But, when the object is lodged further down the trachea it blocks airflow to the lungs. If someone is truly choking, they won’t be able to breathe or talk and their face might turn red. If the brain goes too long without oxygen, damage or even death can occur. Immediate action must be taken.
Why does my motorcycle only run with the choke on?
It means your motorcycle is not getting enough fuel, and this can be caused by dirty or clogged pilot jets, clogged fuel line, clogged fuel filter, dirty petcock, loss of vacuum in the carburetors, among other carburetor issues. Nine times out of ten the cause is clogged pilot jets.
How do you fix choke on dirt bike?
Put the choke on and start the bike up. Once is running, mist some carb cleaner or starting fluid around the air boot and around the vacuum hoses (if there are any). If the engine momentarily races, then you have an air leak. Read below in the section on how to fix air leaks to get this addressed.
Why does my lawn mower run 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.
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 to do if your bike won’t run without a choke?
Normally you would keep it on (closed) until the engine warms up and then turn it off (open). If it really won’t run without the choke being closed/on then it’s not getting enough fuel and the carbs probably need cleaning.
Why does an engine only run on choke?
An internal combustion engine needs a precise mixture of fuel and air to run properly. When the engine is cold, it needs slightly more fuel in the fuel/air mixture for it to start, which is what the choke does. The choke increases the amount of fuel in the mixture, creating a richer mixture.
Why does my Virago motorcycle not run without a choke?
I’m trying to figure out what’s wrong with my Virago 250cc. It will only run if you have the choke on. If you let it off the choke the engine switches off. I originally thought that maybe the carbs were dirty. I ran some Seafoam through the fuel system, but it didn’t seem to help.
What happens if you leave the choke on for too long?
Experiment, you will soon find out what works best for you. Yes, you can do damage if you leave the choke on for a very long time: too much petrol gets into the engine and washes off the oil film, so the piston will have insufficient lubrication. On many bikes you will notice that it won’t run right, but on some you don’t.
