Ron-
Would this only apply to only Ford carbs or would any carb have this same
malady?
I have an Edelbrock 4-bbl on my stock 260 and sometimes have a hot start
problem. It seems like vapor lock but I'm not sure.
I would be very interested in your findings. Please send them to me at:

I have been doing an Original Tiger engine study from the Ford casting #
and
casting date point of view.
I came across a notation about Hot starting and the use of restrictor fuel
bowl vents to reduce fuel vapor in the air cleaner.
The bowl vents are the 2 vertical tubes near the choke plate and restrictor
vents have a smaller hole on top than the diameter of the tube.
There is a Ford TSB covering this; 8/19/63 Ford TSB, Section 1750, Article
#27.
Ford incorporated restrictor fuel bowl vent on Dec14,1962; this would
indicate that all 2bbl carburetors on Tiger engines have these restrictor
vents.
I have also looked at some period pictures of Tiger engines and they appear
to have restrictor vent but I can't say for sure all Tiger engines had
them.
I have had some hot start problems at times with the non stock C7, 2bbl
carburetor on my Tiger so I will have to investigate this more on my
engine.
This should also be looked at with any 4bbl carb if you have a hot start
problem.
It would be interesting to note if all those with the original 2bbl have
these restrictor vents.
As always if anyone needs help deciphering casting #'s and date codes; I
will be glad to assist.
If you are interested in participating in my engine study; contact me on
this List or off line.
