If you'll go to my blog (bobhooversblog.blogspot.com) and enter
BURETTE as the search seed in the little white window in the upper
left of the screen, you'll be presented with an article with the same
title as this message which explains what's involved in adjusting the
volume of your combustion chambers.

Like most of my articles, this one has generated the usual rants from
the guys who have built a million engines without using any of the
procedures I've advocated over the years. The funny thing about those
procedures is that I'm not the guy who dreamed them up. All of these
procedures, in whole or in part, can be found in the Factory Workshop
Manual from Volkswagen. All I've done is 'translate' the procedures
by describing how I did them, or described how to make the tools
needed to accomplish them.

This particular article, having been written in the late 1980's...
back when I was doing everything with film and the drawings in pen &
ink, appears on the blog without any illustrations at all. The
supporting illustrations had to be run through a scanner, then
adjusted for contrast or color balance, then cropped to fit a
particular 'box' in the Adobe file, then.... on and on and on... As
you can see, it never got done. That is, the book of which this was
to be a part, never got written.

Nowadays it's so easy to snap a digital image and insert it into a
file, I'm a bit ashamed for nor having done so with all of these older
articles. But there's only so much time in a day and I somehow manage
to burn it up without having completed all the items on my 'to-do'
list.

For some, the printed word simply isn't enough. They need to SEE how
the procedure is done. So I will try to insert enough graphical
information to get you started.

One thing that many find to be an obstacle is the plastic cover-
plates. Others have trouble tracking down an accurate burette. And
more than a few don't have the rotary tools needed to ENLARGE the
combustion chamber. That's all you ever need do, you know... make
the LITTLE chamber(s) bigger. And as with computing Compression
Ratio, you are not required to do all FOUR chambers nor cylinders, you
must simply adjust the THREE to match the ONE which is of the proper
size... or as near to it as you care to go.
