<VV> Unvented Gas Cap? Re: strage thing with my 66 Corsa

[FrankCB at aol.com]

Hi Ulli,
 
One possibility is that your gas tank is not vented.  As the Corvair  
engine runs, the fuel pump pulls gasoline out of the tank which must be  replaced 
by air entering through the VENTED tank gas cap.  If the  vent is blocked, 
a vacuum gradually builds up in the tank which will  prevent fuel from 
leaving the tank and flowing to the fuel pump.   If your level of fuel in your 
tank is well below the "full" level, try  running the engine with the gas cap 
removed.  If this solves your  problem, then replace your gas cap with a 
stock Corvair vented cap.   The correct cap will make a rattling noise when you 
shake it demonstrating  that the venting valve is working correctly.
Good luck and let us know if this solves your problem.
 
mit besten Wunschen,
Frank Burkhard

Hi to  all,

I passed inspection on yesterday, go it licensed today. Everything  fine so 
far.
Drove to work this morning - fine. Got back into the car after  work, it 
started right up, backed out of the parking lot, put in the first  gear, 
second .... engine died while driving. Wont start after that.
I  waited for about 15 minutes tried it again: starts right up, drives in 
first,  as soon you shift into second engine shuts down.

Now I am back from a  30 minute foot walk and I do hope that any of you 
Corvair specialists   has an idea of what is wrong with my  baby.


Regards
Ulli
