Not familiar with s3 cars
Do the carbs have heat compensators on them like the series 2 cars
There is an idle trim screw on them used when the engine is tight one on each compensator
I believe when seated will cause engine to increase rpms , open up to decrease fuel

When stowed in bag (jack and wrench, hammer, brass knock off socket) fit easily into wheel with a roll up toolkit beside it.
