The available zoom levels has been an issue with the Jetbooks for as long as I have
been looking into it. The contention has always been around the size of the steps
near the default 200%. (For those with the 0.16 FW who might be confused at this
point; you can see the % numbers by going to "Settings">"Zoom Level" with the "Menu"
button.)

I find that there is a great deal of difference between the display of the PDF with the
Reflow ON compared to with the Reflow OFF. (When you go to the Menu and there is the
option "Reflow ON" that means that the Reflow is off.) With Reflow off the "Full Screen"
and "Fit Width" options are available/not disabled, and the page is displayed as if it were
an image of the full page. This provides the best display of the graphics and text
features, as they would normally appear if the screen of the JBL were large enough to do
the page justice. To be able to see parts of that full page image, at a larger, more
readable, size on the JBL's smaller screen you need to zoom into the image.

With the Reflow on (and the Menu item "Reflow OFF" showing) the Text is treated as
separate from the graphic data on the page and the text display on the JBL can be
formatted to fit the JBL's screen size.

Now to address your question, I don't know how Adobe is implementing the Reflow or
if the Adobe Mobile Reader as implemented on the JBL offers any ability to control the
display of the Reflowed Text, for font size or line spacing. I would guess that the reflow
starts with the text from the PDF at a size related to the normal full page display of the
PDF. Zooming with the Reflow on could be effectively zooming the page image of the
PDF that Adobe is using to extract the Text for reflow. But I don't know.

At this point it may be that you will have to live with the limited zoom options of the
Reflow mode, and the resulting effects on text size and placement -or- Remake/Edit the
PDF to match your preferences and the display parameters of the JBL, then view it with
Reflow off.

Luck;
