Why does my carburettor keep bogging down?
The job of a carburettor is to atomize liquid fuel by injecting it into a flowing stream of air. The mixture of this air and fuel must be rather precise in order to combust within the cylinder. If there is much air, or too much fuel being delivered you will experience power loss and/or bogging down.
What causes loss of power and bogging down?

Why does my car lose power when it gets up to temp?
My car has an automatic transmission. Heat causes electrical resistance in a circuit or component to increase.

Also, heat can cause a crank position sensor to act up if it is starting to fail.
What causes a boat to sputter and lose power?

Can a bad throttle position sensor cause idle surging?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS.
