Why does a carburetor bog when the throttle is opened?
When the throttle is opened, there is now sufficient velocity of air to sweep all these droplets into the cylinders, creating a mixture which is too rich to burn, hence the bog. As soon as the overrich mixture is pumped out the tailpipe, and a normal mixture is ingested by the cylinders, the bog disappears.
Why does a Double Pumper carb bog down?
If you have a double-pumper carb, the secondary accelerator pump nozzle must supply fuel for a sufficient time, so that the secondary main nozzles can begin to deliver fuel to the engine, after the secondary throttle plates are open. Otherwise this will also cause the engine to bog.
Why does my pit bike Bogg down when I accelerate?
Most pits will do the same if you really whack it back fast and all the way. you can make it better and more/faster response by fitting higher quality cdi’s and super coils and all that jazz.
What happens when you open the throttle on a gas engine?
This will cause a phenomena called “puddling” where little droplets of gasoline adhere to the intake manifold runners. When the throttle is opened, there is now sufficient velocity of air to sweep all these droplets into the cylinders, creating a mixture which is too rich to burn, hence the bog.

Why does my bike bog at the wrong time?
When the bike is at an idle, it will bog if you open the throttle all the way to fast. It is still rideable but sometimes when it happens it is always at the wrong time. My plug is lightly oily and black. I already cleared my jets and cleaned the carb. Thanks guys. You’re running rich man.
What to do when your motorcycle jetting bogs?
You’re running rich man. When the temps change you have to change your jetting although you can easily take away that bog (rich) by leaning out the air screw. If you know where your air screw is at on your carb turn it counter clockwise in 1/4 turns until it revs perfect. Turning this screw clockwise will rich the mixture and worsen the bog.
