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

It sounds like the secondaries are the likely problem.  If you very
gradually open the throttle until wide-open, does the engine still stall?
When the secondaries are opened suddenly (engine off), do the secondary
squirters produce a strong jet of gasoline?  If not then the secondary
linkage, accelerator pump and accel pump linkage should be checked.

Hi all,



I've had some off-line conversations over the past day with a few people
regarding my carb cleaning. There may be some general interest to the list,
and I've lost track of who I have said what to, so the easiest is to just
post to the list.



I pulled my carb off over the weekend. I removed both bowls and found a
surprising amount of fine sand-type stuff inside.



I removed the floats and cleaned out the bowls. I cleaned up everything the
best I could and re-assembled.



I installed the carb and fired up the engine. I noticed two odd things -
first what appeared to be a spurt of fuel out of one of the vents, but I
didn't see it again.



The engine fired up and ran pretty well, but if I give it full throttle, the
engine dies. If I release the throttle, the engine catches again.



Note that it did NOT do this before I "fixed" things.



The carb is a Holley 700DP. It'll run just fine at any rpm as long as the
throttle is less than half open, at which point it stalls.



What did I screw up? How do I unscrew it up?



Thanks!
