Why is my carburetor not getting fuel?
No fuel at your carburetor can be caused by many things. It could be a simple issue like a fuel filter plugged so tight that no fuel can pass through. Another logical cause could be the fuel pump. A hole in the fuel line on the tank side could also cause the fuel pump to suck air instead of fuel from the fuel tank.
Why do you rebuild a carburetor?
Since the ethanol in gasoline breaks down the gaskets and other rubber components in the carburetor, these days you will find it necessary to rebuild your carburetor when the parts become cracked or brittle. A well-maintained carburetor will only need a rebuild every few years when the internal components begin breaking down.
What are the symptoms of a dirty carburetor?

Why does a carburetor only work with the choke on?
If you have a choke lever separate from the throttle and the engine only stays running when choked, then your carburetor has a fuel blockage causing it to be too lean(not enough fuel). The only way to balance the fuel air mixture is to restrict the air by choking it. That’s why it runs better on choke.
What are the symptoms of a bad accelerator pump?
