Mark,
The Smart A... answer is that if it walks like a duck, quacks..... You have
too much air getting in somewhere.
Since you mention that the compression is up, and that you had the head
worked on start at the head gasket and work out. Is there any discoloration
to the oil (from water/gas contamination)? Look at the intake manifold to
head gasket and make sure that it is intact. I really think you'll find
your problem in one or both of the carbs. Make sure that all places that
have access to the outside world from the guts of the carbs are blocked off.
For the purposes of your test you can literally take every hose (except gas)
off the carbs and block up the respective holes.
As I sat and did this epic answer a light bulb went off. What's your fuel
pressure and does it flow is a nice full stream. You might have a dead fuel
pump, bad filter, clogged screen in the fuel pump,etc
Good luck
Steve

Aloha All,
I really need the help of the group. I am stuck on an island here
(literally)
and my local resources are kind of low. Quick recap: I bought a '74 TR6 in
December from Indiana and drove it accross country, 2500 miles without any
major problems. Shortly after I got it home, both carbs started leaking.
Instead of just fixing the leak, I took it upon myself to undertake my first
real stab at being a mechanic and rebuilt the carbs with a kit from TRF.
>From that day forward (it was about mid January) my car hasn't run. After
many trials to get it going, I realized that I should do a compression
check.
I had 40 in 6; 90 in 5 and between 110 & 120 in 1 - 4. The head was rebuilt
shaving it down to 9.5:1 compression and just put back on the car about two
weeks ago.
I haven't been able to get it running since. Observations: 1) it will not
idle w/o the choke on and even then it's very rough. 2) When you give it
gas,
it sounds starved for fuel (makes a loud boggy sound and then cuts out) 3)
EGR
valve is not holding suction as per the test suggestions provided on the
list
(removing the vacuum hose, pushing up on the diaphram, plugging the vacuum
hole with my finger and seeing if it holds) 4) We will be doing a smoke test
tomorrow night but haven't done any thorough vacuum tests to date 5)
Currently
have 140 - 150 compression accross the board 6) timing is fine 7) New coil,
plugs, wires, rotor, condenser; rotor cap.
I am suspecting that this has somthing to do with a serious vacuum leak
which
we should gather more inforation after the smoke test but am also feeling
that
there might be something more. I've taken the carbs apart more times than I
care to remember and am very close to sending them out to have them
professionally redone but can't really see that there is that much that I
could have really screwed up in the rebuild.
My sincere apologies for the long post and heartfelt thanks in advance for
the
answers but I am really at a loss. I am new to cars in general and while I
have a very good friend who is a terrific Ford mechanic, he is also at a
loss
with my lbc. I have to say that I am getting very frustrated with my lack of
knowledge on the subject and a local resouce to turn to. You guys are the
best!
Warm Regards,
Mark Bullard
