Carburettor
In Turkish: Karbüratör
In short
A carburettor is the mechanical fuel system component that mixes petrol into the incoming air in the correct proportion.
As air passes through the carburettor's narrowing throat (venturi) it speeds up and its pressure drops; this pressure difference draws petrol from the float bowl through the jets. Main parts: float and needle valve, pilot (idle) jet, main jet, jet needle and slide (vacuum or mechanical).
Common problems
- Hard starting, stalling at idle – blocked pilot jet
- Misfiring, loss of power – dirty jets, air leaks
- Fuel overflowing – worn float needle
On bikes left standing for long, petrol can go stale in the carburettor and clog the passages. Because of emission rules, most new motorcycles use fuel injection instead.
