Fitting Ivan’s slip on kit, who does it now ?

[Falcon 269]

With the throttle slide springs, simply cut them and then bend the cut end down until it's parallel with the uncut end.  That's enough to stop it snagging in the carb top.

Although Ivan says you can cut up to 3/4" of an inch off the spring, I cut no more than 1/2" off.  The reason is that the springs take a bit of a 'set' over time and become shorter than their new length.  Too short and the throttle response can get a bit unpredictable when you open the taps smartly.
