Interesting article Russell,

To improve this article you could perhaps discuss,
- Vacuum operated secondary butterflys. How they work and can be adjusted.
- Power valve operation.
- Idle transition to main circuit.
- Main circuit description seemed light on and no discussion of elmusion tubes.
- What causes poor idle adjustment on modified engines and strategies to compensate. ie air bleeds.
- Importance of correct fuel pressure regulation and float level adjustment.
- You discussed booster venturis but no discusson of main venturies.

Just some thoughts,
Chris.

Thanks for the comments CS123 -

These articles are primarily designed to cover the topics in brief and by necessity some things are left out or not covered in detail as the target audience is the complete novice.

Future documents will delve into the "How To" in a similar fashion to the one about Ignition Timing.

There will also be other more detailed docs that look at some of the components in greater detail and there will be a series of documents on modifications as well.

All of these documents should probably be prefaced with the comment that they are BASIC in nature.

Cheers
Russ
