After the conversion to the Scalded Dog inlet manifold and Stromberg 97 carb there has been some slight throttle sticking issues. The majority of the issue had been cured by the snap shut device provided by Stromberg

Snap Shut Device

Despite this the throttle still occasionally sticks a little due to the nature of the linkage.

A spring was needed and not one that was too heavy which would add to an already fairly stiff throttle action.

I couldn’t really find what I wanted so I decided to create something out of some small springs that I already had, plus an electrical connector to allow for some adjustment once fitted.

This worked out well and I was able to adjust the tension after fitting. You’ll notice the use of some heat shrink tube to make things look tidy.

So far so good!
