Stall speed of your clutch - WHY WON'T THAT DAMN THING IDLE?






Question: do you know the stall speed of your clutch? At what RPM will your go kart stall?







What to know in a nutshell: The adjustment screws of the clutch can be turned in a certain direction for a certain amount to tweak the stall speed of your clutch.







More questions: What is the optimal setting?


Trial and error where u aim not for a specific RPM but the setting that allows a kart to accelerate out of corners the quickest.





How do i do this??



Well, if you are a beginner hobbist like me, i would suggest to just follow online advice (read:me) and set up your kart first and later build up a feeling for how u want your kart to operate.



Instructions



1) Finding your kart's clutch speed.



- Place your kart flat on the ground with space infront to move. (i.e. driveway, track, etc)



- Start the kart and switch on the RPM gauge.

- Set the Carburator needles so that the engine can be started.


- Keep your foot on the brake to prevent the kart from surging forward and do not release!

- Start the engine and keep it at idling, with the accelerator if needed.

- Take the reading of the tachometer and keep a close watch on it.

- Now release the brake and floor the accelerator.

- You will notice that as the engine revs up and begins to accelerate, there will be a space of time where the RPM does not move before it begins to increase again. That RPM value is your clutch's stall speed.
