Agreed with below but would add any vacuum leak, check your timing. Bad
timing can cause poor idle and heat.

Subject: Re: [Tigers] Stalling at idle
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
