A quick thing to check that happened to me was a leak  in the PVC line.  If 
it's sucking air it won't close the pvc valve at idle  as it should and the 
car will run too lean and stall.  Or if the pvc valve  is gummed up and 
stuck it might display the same symptoms.  When  you shake the valve you should 
be able to hear the ball roll around  inside. 
 
Oh, and since you lowered the idle last year, make  sure the idle screw  is 
actually touching and holding the throttle open a  smidgen.
 
At 214 degrees it's hard to believe it's heat related,  but I'm sure other 
will follow with more items to check.

Hello  All,

Yesterday after a short 20 minute drive I noticed some coolant on  the 
garage
floor from the expansion tank so I checked the temp with a laser  
thermometer.
It measured 214 on the manifold near the temp sender and  thermostat. I did
some tweaking (a thanks to Tom Parker) which included  tightening all hose
clamps and tightening the fan belt. For background, my  260 has the the LAT 
1
Induction system and the LAT 20 perfromance cam. I  have a stock radiator, 
horn
hole covers and a 6-blade fan.

Today, to  check on my tweaks I took it for a longer ride, almost one hour. 
 It
included highway and traffic, in fact I got caught at a RR crossing for  5
minutes. When I got home I noticed the engine was running a bit rough at  
lower
RPMs. I let it idle in the garage but it stalled after about a  minute. I
started it up again (a couple of tries--usually turns over first  time). I 
let
it idle but again it stalled. Did it again, this time I  increased RPMs to 
see
if it was getting fuel...revved up fine. Brought it  back down to idle and 
it
stalled again after a bit.

I checked the  temp readings again with laser thermometer: 214 at Temp 
sendr,
208 @  thermostat, 214 @ radiator, and 198 @ expansion tank. No fluid on  
floor
from expansion tank.

Sorry for the long-winded  explanation...here is my question.

Is this heat related or do you think  it is something with the carburator. I
lowerd the idle last fall because I  thought it was idling too fast...now 
after
operating for a while it  stalls.

OBTW...it was a beautiful drive and the car ran  fine.

Thanks

Jim  Lindner
