Frequently asked questions

What is the 601838 special nut used for?
The 601838 special nut is the butterfly spindle nut for the carburettor. It secures the throttle butterfly disc to its spindle inside the carburettor body, holding the disc on the shaft that rotates to meter the air and fuel mixture into the engine. It's an OEM nut.
Where does the butterfly spindle nut fit?
The butterfly spindle nut fits inside the carburettor body, on the throttle butterfly spindle. It retains the butterfly disc on the rotating shaft. Because it sits on the spindle within the carburettor, you typically reach it only with the carburettor off the engine and partly dismantled.
Should the butterfly spindle nut be replaced when removed?
It's typically wise to replace the butterfly spindle nut whenever it's disturbed. These small carburettor nuts are often staked or thread-locked to stop them backing off into the engine, so retention can be compromised once undone. Fitting a fresh nut helps keep the butterfly disc secure.
