Why does my bike shut off when I take the choke off?
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. 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 riding mower only run on full 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.
Can a car run with the choke fully off?
Yes the engine is supposed to run with the choke fully off (or open). If you have an n.t. carb, the choke will be a simple, old style plate that opens and closes at the inlet of the carb.
What happens when you close the choke on an n.t.carb?
If you have an n.t. carb, the choke will be a simple, old style plate that opens and closes at the inlet of the carb. If you have to close the choke, it’s telling you that you are getting too much air (making it run too lean). When you close the choke on an n.t. carb you are restricting the amount of air that the carb sucks in.
What causes engine to stall with choke fully off?
Screw it out, the slide closes and allows less air AND fuel to get sucked into the engine which will make the rpms go down. this has nothing to do with the choke. My bike was doing the same thing, and I rode it that way for about 4 months. Then it sat for a while, and the fuel went bad.
Where is the choke on a Honda lawn mower?
Down here Honda give 5 year warranties on their engines and some parts are lifetime for the original owner. And are you sure that the choke is actually on when you think it is on. The choke butterfly is at the front of the carb and you would not be the first person who thought that the choke was on when it was actually off. Thanks.
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 happens when you turn off the choke on a Honda lawn mower?
It starts immediately with the choke on. When I turn the choke off, it sputters very heavy and shuts off. I am running 100% pure gas with no ethanol now. With choke on, it pretty much purrs. When choke goes off, it dies, sometimes within seconds.
Can a Honda gcv190 run with no choke?
I am running 100% pure gas with no ethanol now. With choke on, it pretty much purrs. When choke goes off, it dies, sometimes within seconds. So based on reading online, the default answer seems to be a plugged jet in the carb. Well this is a brand new carb so I don’t think that can be it now.
Why does my car stall when I close the choke plate?
Starts and stalls within a few seconds: If the choke plate closes properly and the engine starts and stalls almost immediately, the issue is usually not choke-related. This condition is likely the result of the carburetor float bowl losing fuel when the engine is turned off.
