[DeTomaso] RV: New Pantera owner on Long Island

[Charles McCall]

Hi Robert

I've sent you two documents, which the list will strip for the rest of the
subscribers. (If anyone is interested in a copy, let me know)

One is the Holley Service Manual. The second is the Dan Jones Holley Tuning
Manual. If you don't know Dan, he is a frequent contributor to this list,
and is generally acknowledged as being a god. He also has tuning notes from
other DeTomaso celebraties such as Ted Mitchell, etc. 

If you are a real gearhead and you enjoy messing with engines, these may be
useful. If you are not, you can drive yourself crazy trying to sort out a
problem carb. 

Do you have a known good carb you can try to see if the problem is truly
carb related? (as opposed to, say, timing or a partially sheared distributor
pin, which is kind of the same)

It still sort of sounds like your choke isn't working properly, or at all...
Or is working backwards somehow? Lean at startup, which is why you need to
give it gas to keep it running, but then rich when warm?

Best bet is borrow a known good carb - it doesn't have to be a 750 (which
many feel is too big a carb for a 351C anyway) it could be anything from a
600cfm up. 

Good luck - you'll be thrilled with the car once you get this issue taken
care of!

Asunto: [DeTomaso] New Pantera owner on Long Island

Hello All,
I am the new owner of the 1972 Detomaso Pantera That Boyd was talking about

yesterday. The holley 750 (3 yrs old) that is on the car had the choke wired

open and held in place .The car has been running extremely rich since I  
purchased the car. I went to my local speed shop and purchased a holley
matching  
electric choke. I wired the hot wire to a 12v ignition controlled wire.
Ground  
wire connected to the carb itself.At ice cold start I turn the key on 
....pump  gas once and hear the choke engage.Then I turn the key and she
starts up 
....low  idle and will flutter out unless i control the gas peddle myself to

keep her  running. I have also tried readjusting the four tiny screws at the
four 
corners  of fabulous holley carb.I have backed each screw all the way in and

then back  out 1.5 turns .I have then adjusted each screw for highest RPM.
The 
car feels  like she is missing or tugging and I know its the carb. When i 
shut her down she  sometimes blows a flame out the tailpipes. Any ideas?
Blown or 
wrong power  valves installed? Stuck float levels? 
All of this seemed to start right after I installed the electric choke. Car

was running rich before the choke by the way . Fuel pressure is at 7. vacuum

approx 13. Mallory electronic ignition. Plugs are dark with less than 1000  
miles on them
