## What is wrong

THE HOOK SIZE OF THE THROTTLE RETURN SPRING IS TOO SMALL RESULTING IN A TIGHT FIT AROUND THE ANCHOR NUT, CAUSING THE THROTTLE RETURN SPRING TO BREAK PREMATURELY.


## What can happen

IF THE THROTTLE SPRING BREAKS, THE ENGINE WILL RETURN TO IDLE SPEED, WHICH MAY CAUSE A HIGHWAY HAZARD AND RESULT IN A VEHICLE CRASH.


## The remedy

INSTALL THROTTLE RETURN SPRINGS WITH LARGER HOOKS.
