Without an air vent the fuel would not flow to the carb.
Any empty tank is really a tank full of air. If you want water to go into a tank or pipe or drain then you have to allow the air to escape out of it. We allow the air to escape through a "vent pipe," connected to the tank. When refering to septic tanks, this pipe is called a "septic tank vent." Unless we use a zeocarbon filter on the "septic tank vent", the vile air coming out smells like a combination of rotten eggs and ammonia. Some septic tanks are upgraded to include aeration systems where electric or solar powered aerators bubble air into the liquid in the septic tank. Although these systems treat water faster and produce cleaner treated wastewater you still need a "septic tank vent," to let the air escape from the tank so water can go into it.
The 2013 Honda Rebel motorcycle features a 234 cc air-cooled parallel twin-cylinder engine and a five speed transmission. The Rebel also offers fuel economy at an average of 84 miles per gallon. Full specifications are available on the Honda website.
it is to allow air to enter the tank to replace the space that the gas was taking up.
check the freon and cabin air filter
under the gas tank...
2 turns out from seated is a good start
under the gas tank
Clogged fuel tank vent. As the fuel is removed air must enter the tank or it will collapse. Can be nothing more than a defective fuel cap.
the air filter is located under the gas tank, remove the tank, and change the air filter. SOME air filters are reusable however.
I don't know if this will help you, but I have seen this on newer Honda Generators. The new ones have a small slide switch on the gas cap that lets air in. It can be turned off for travel. However if it is left OFF when the engine is started it will cause a vacuum in the fuel tank and starve the engine. Take your gas cap off and see if the air vent plugged (If it has one) This may be the problem. Or put about 1/4 tank full of gas in the generator and see if it keep running without the gas cap on. If it does, it's a plugged air vent in the gas cap.
The air filter is under the gas tank
No. You vent air from a sewer line.
