Tips
Don't waste your money on a new carb if your engine
is near death. Check the
compression, adjust the valves, make sure the
ignition system is optimal, and
get help if you're not sure about doing the job.
Preferences
I always used to put on 32/36 DGAV carbs but am so
happy with the 38 DGAS
that that is what I am recommending now.
Cost
$400 to $500 with a quality air cleaner depending on
the source.
Mileage
20ish around town, 25 or so on highway. It depends
on your driving style, the
differential gear ratio and whether or not a 5-speed
is in the car.
Improvements
The 38 DGAS is much, much smoother than a 32/36 due
to both barrels opening
together, eliminating the bog at midrange that
occurs with the 32/36 during
acceleration while the secondaries are opening. At
3,000 rpm, the primary
barrel of the 32/36 is too lean and causes a surge
due to being undersized
for the task.
Modifications under the hood
The intake manifold needs to be removed and modified to match the base gasket area to the base gasket configuration of the new carburetor, which usually means a little grinding to open up the inlet holes of the manifold. The stock air cleaner also is removed, and a K&N is the best choice for ease of fitment and longevity.
Postscript
Enjoy the new power you didn't know was hiding in
that little engine!
