Another question would be are people using the right airfilter. There is
one for this carb that is 1" taller than the one the spit is supposed to
use.

Subject: Re: Replace ZS Carb with Weber DGV
The Pierce intake manifold has 1/4" more offset than the Cannon intake. I
sure
would like to know why some people are able to use the Cannon without
problems
while others have dings in the hood where the air filter hits it.
The extra 1/4" should be enough to clear my hood. I will know in a few weeks
when that part of the project comes up. I have a few other things to do
first.
I'll update the list at that time. I may take pictures and post them on my
web
site too.

The water choke works with the engine, and releases the choke as the engine
needs it. A far superior way to do it.
