Hello i have a year old harder and steenbeck evolution airbrush that isn't working very well at all and was hoping there's someone who knows about airbrushes and could take a look at this one for me or recommend someone thanks John . You can contact me on [email protected] thanks

Do you have a local hobby shop that you can take it to, for an inspection?
or
if you are at easy with taking it apart, do so and give it a good cleaning.

In many cases, a good cleaning usually resolves many problems.
Cheers,

Here's a vid on cleaning and maintaining a H&S Evolution:

There are other vids on troubleshooting and repairs.

If you can't get it working you could contact the folks at Airbrushes.com - they are on the south coast and not only sell ABs and spares, they also service them.

ThAnk you al for your time very kind Ii will check out the video here's hoping cheers john
