[Spridgets] Weber DCOE vs OER DCOE

[Robert E. Shlafer]

LOL.... :):)

..there are a lot of things it's possible to do that maybe we shouldn't do!! And as we gain experience over time, we're usually appreciative of the fact to one extent or another we survived and are still alive! :) 

Now, seriously...

DCOE vs DCO.....

....according to Passini on Weber (I don't "know" mind you, just the messenger) "a DCO is not at all a DCOE".

Now.....he never explained ALL or any of the "differences" and I've no knowledge or experience with a DCO...so I've no real clue on this. I simply don't know, Daniel.

Hi Cap'n,
 
What I meant was:  If it's a bad idea, which it is, why is it possible  to 
implement such a bad idea?  For example the smallest size main  venture you 
can put in a 48DCOE is 40 (which is the max size for a 45DCOE), yet  later 
on when the 48DCOE was replaced with the 48DCO the smallest size main  
venturi was 42.  Also, on the 48 DCO (not sure about the 48DCOE) there is  no 
provision for a cold start device with the carb simply being cast smooth at  
that point.

Too much  "squeeze down" of inbound airflow....high airflow "drag" numbers 
accordingly.  I forget the exact name of this
type of "drag", but this effect also makes  for less accuracy in metering 
with respect to progression, jets,  etc.

Basically, too much carb for the application.

Anything  below 34mm chokes, better all-around flow velocities, etc. with 
the  smaller
40.

If you choke a 45 down to a 32 choke it generally  flows less and doesn't  
perform as well as 40 in the same size.   That of course begs the question  
why it's possible to choke down if  it's a bad idea - I don't have an  
answer.

They  don't stock the OER
in  anything smaller than 45, and the minimum venturi  size is 32
