Andy,
If you think that's the problem you can get a heat spacer that goes under
the carb for about $10 through Summit. I was getting the problem when I
shut down....had a hard time restarting. The spacer solved the problem 100%.

Guys:
After all the stuff I've done to the Tiger ignition-wise to get it to quit
stalling, I'm finding myself starting to consider other possibilities,
such
as vapor lock and fuel percolation. To make a long story short, the car
is
leaving me on the side of the road when it's up to operating temp and warm
outside. It caughs and sputters and won't take any throttle at all at low
rpm. When I coast off to the side of the road and take off the air
cleaner,
I'm seeing what I would consider to be a large amount of vapor coming from
the overflow tube (Holley 465 4 bbl). It also periodically spits fuel
from
the center squirter down the throat of the carb. From what I've read on
the
'Net, this sounds like a classic case of fuel percolation. One other
thing...the car will always start back up and run, but will not take any
throttle or any low rpm load. Also, when I manually open the throttle, I
am
rewarded with fuel squirts (at least I know it's got fuel in the carb at
that point).
What I can't figure out is, if it is percolation, what has changed to make
it do that? I've made no changes to the fuel system of the car. In fact,
until the recent ignition tune-up, I'd made no changes to the car for
many,
many years. It's never done this before. The car is also running at the
same temp it's always run at. Could the gas we're getting nowadays be
responsible for this? I always run 91-octane premium (real gas, no
ethanol)
and have for years. I've heard there is such a thing as "winter mix gas"
and "summer mix gas" and that each have a different temperature at which
they volatize. Due to some serious drains on my time lately, the last
time
I filled the car up with fuel was in May. Could I just simply have a load
of "winter gas" that volatizes at a lower temperature?
Any suggestions??? Please somebody send me to school here...I'm beginning
to feel really stupid.
