Wow just and excellent video cause lately I have been having problems with my go kart when I press on the gas too hard it cuts so I guess it has to do with the float. Thanks again

@george2011k Yeah you can run out of gas if you are flooring it for extended periods. The rememdy is a bigger bowl, or a bigger carb can help with the running out of gas problem. If it is the original engine on the go kart then you may want to look at the adjusment of the float. Be aware that if you make the float adjust to close to late (ie doesnt float enough) the gas will may drip out of the mouth of the carb, not a desireable effect....

Great question. The vacuum results this time, because the engine is drawing in air. Air has to come from somewhere, so instead of going through the main throttle body, it goes around and through the fuel bowl drawing a ton of gas into the throttle body. The venturi effect does not come into play when the choke is on in other words; the vaccum, you are correct does not come from air flowing over, but air being absent because it is being blocked by the choke plate: hence the name "choke."

Cool, Very informative, are most/all carburetors like this? i remaking a custom/modded 60's jeep with transplant carburetor engine.

@Foobyking9000 Most simple carbs are like this. Larger carbs on V-8s can be a bit more complicated having variable adjustments built into them but this is mostly for when you stomp on the gas the engine needs lots of fuel to get up to speed, so there are accelerator pumps and jets that pull out dumping gas into the manifold. Other than that the principles are the same.

@gamblighini shit,

the one i got is v8

[gamblighini]

@Foobyking9000 On v-8s there are several different types of carbs. The two barrel and the four barrel. The two barrell means it has two venturis and two throttle plates. It also has two jet adjustments. The jet adjustment is done by a couple a methods, using a test light and examining the spark plugs for color. The plugs should be a tan color. White means that the mixture is too lean. Black means it is too rich.

The four barrel is similar, and has two jets for adjustment.
