.......This may sound really stupid.... I don't know how long you have had the
car. Check the fan rotation and make sure the blades are not on backward.
My car did the same thing as yours when I first got it (it had dual carbs back
then) ....the previous owner had put the cooling blades on backward, and the
car only "vapor locked" at speed on 80 deg+ days. ..It drove me crazy for a
while....

Subject: Vapor Lock Symptoms?
Hi folks,
My 60 BN7 appears to have one carb acting up or vapor lock or???
It happens after the car gets very warm. The weather has been in the 80's
lately and it never did this before. I thought I found the problem. The
linkage was loose between carbs. I tightened that and all was well until
today when I went for a long hard drive.
What are the signs of vapor lock? The fuel pipe carb to carb feels very hot
to the touch though my temp gauge never goes above 180. Could the heat cause
a problem btween carbs? Would the braided fuel lines help? Should I consider
this a potential problem?
My points look good. I have yet to pull the plugs because it happens
intermitently but I have been told to through away these Champion plugs. I
have new Autolites ready to install.
I have new plug wires and cap.
I suppose a float could be sticking or I may have some dirt in a jet etc.
I'm just wondering why it gets worse as I get warm.
Thanks for any sugeestions.
Cheers,
Scott
Mashed BN7
