The Chirco Air-Cooled forums have become quite a data base of air cooled knowledge.
It's just finding the information that answers your question that gets tough.
Always feel free to post up a new question at any time.
Here are some quick tip's to searching
The easiest way to find something is to use the quick search in the upper right corner.

Or you can choose the search feature in the menu bar just right of Help.
The will also get you to the advanced search option.

From this screen, type in your keyword and it will produce the same result
as if you did a search from the upper right hand corner.

In the lower left, you will see advanced search, click that to open the
more defined search features of the site forums.
The first example is searching for Baja Bug and show results as a message.
This will show Threads that have the term Baja Bug in it.

Here is an example of the search results.

Choosing to show the same term in Topic Subjects Only will show you
posts inside of the threads.

Here is an example of that search.

To find what you are looking for, use smaller words and short phrases to
start. If the search result is huge, then start narrowing down by adding words.
I hope this helps
