EP2: Cleaning the HS4 SU Carburettor | CLASSIC MINI 25 RESTORATION

Welcome!

This episode is about cleaning the HS4 SU carburettor of the classic mini.
The carburettor will probably need a full rebuild kit, but for now I'm just cleaning and inspecting it.

Feel free to leave a comment!

Kind Regards

This is the best way to show this process. No audio needed just clear video. Well done.

Excellent video. Did a similar but not as good job on my HS4 recently, came across your video trying to learn more about them. Very useful insight into the parts. Thank you for making and uploading this

i recently bought myslef a mini and believe to have one of these HS4 SU carbs with the waxstat at the bottom...im going to attempt a service on this, never done anything on a car before but this video has shown its not as difficult as i thought it would be, brillaint video

Hi excellent video, I’m having problems with my mini pickup which has this exact same carb. It’s not ticking over right, also when going round sharp corners (turning left) it cuts out, do you think it could be the float? Also did yours run a lot better after this video? Many thanks

Thanks. You’ve gave me the confidence to tackle mine.

Excellent presentation. Somehow I did not miss the voice or some horrible music ! I am assuming you did not remove the metering needle from the piston. Any reason for that ?

I also have the FZX1415 HS4 carb on my Mini. I recently bought an SU tuning/servicing book and although hundreds of SU's are listed, this particular one is not present in the appendix tables. Any idea what the differences are? Are you planning to show how to center the needle & do the "drop" test on the piston?

Hi, great video! but i have a question, What book did you use in the video to see how to assemble the carburettor again?
Thanks!

[diegocaceresfuentes]

Excelente video, yo tengo el mismo carburador y no me atrevía a intervenirlo. Ahora lo haré con toda seguridad

Hi from Chile. We are restoring a 1982 Austin Mini HL that has been unused for over 15 years.
With what liquid are you cleaning the parts? This is a father and son project. Thanks.
