[DeTomaso] OK, now what did I screw up?

[Charles McCall]

Hi Sports Fans,

Thanks for the help during the past few days. I now have the carb off the
car and am investigating. 

1) The linkage associated with the secondary side is working just fine. As
soon as the butterflies begin to open, fuel begins to squirt as it should. 
2) With the carb on the bench, opening the fuel float level window results
in a flood of gas... apparently the secondary side bowl was completely full.
The question is why? 

The floats appeared to move with no problems when I had the carb apart, so
while it would suggest a needle valve stuck open, or a stuck float, that
would be somewhat unlikely. 

I'm now disassembling the carb again to see what I see inside... stay tuned!

Charles, I agree with postings saying this must be related to secondaries.
First, is it getting too much or too little fuel at WOT? Can you drive at
WOT so it dies? Then pull over and take out plug, is it wet with fuel or
bone dry? I guess bone dry. 

Secondaries probably open as they should, but either the secondary float
level is too low or secondary acc pumps done work. Both can be tested with
car standing still. See float level through window at idle, and check acc
pump squirt with mirror with engine not running. Adjust/repair.

If these things are OK, then it could be some goo/sand/dirt thing somewhere,
use carb cleaner and compressed air all over secondary part of carb.
