Setting up / Tuning an HD6 Carb

[ianh]

Hi,
Does anyone have a good guide to setting up / tuning an HD6 SU carb. ?
Thanks
Ian

PS
Will be doing it initially without the benefit of specialist tools

The service manual and Tech Talk by Nock are valuable referances as well. I use several different tools for the job, a unisync, colortune and the SU tuning kit. I have never had great luck with lifting the pistons and rely mostly on getting the basics set and then reading plugs.

There's quite a bit of info on the internet about tuning SU carbs--I had no trouble finding several good articles with Google.

If you don't have a Uni-Syn, you'll need a length of hose with which to listen to the airflow.
