<DIV><FONT face=Arial size=2>My two cents-</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>While I may be new to the club I have had a lot of
old cars and trucks, including many Corvairs, and I have spun a lot of wrenches
on them. I know that somone will beg to differ, but everytime I have heard
of a problem and it is attributed to vapor lock - it isn't. While vapor
lock was common on very old cars because of the lack of a fuel pump (engines
were gravity fed from a tank in the cowl), it simply doesn't happen often on
anything with a fuel pump. It also can't happen when the car is
running. The theory behind vapor lock is that the gas gets heated in the
lines and vaporizes causing a non-start problem on a hot engine that has been
recently shut off (hot soak condition). Fuel in motion will not tend to
vaporize in the line. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It does not mean that the problem is not heat
related, I just seriously doubt it is vapor lock. I have
gotten Corvair engines super hot and ruined them in the process, but
never experienced a probelm with vapor-lock. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So what to check?</FONT></DIV>
<DIV><FONT face=Arial size=2>I have seen ignition coils go bad when they get
hot, a condenser that goes bad when hot, and bad connections to the
ignition. When this happens again, check for spark. it is still
possible it is fuel related, like a fuel pump problem, so pull off the air
cleaner and look down the primary carbs with the engine off, push down on the
accelerator linkage and see if you get a "squirt" of fuel, if ya do - it isn't
vapor lock. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Good luck </FONT></DIV>
<DIV><FONT face=Arial size=2>Dave</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>PS - Just recently I had a problem on my porsche
that the prosche club members told me was vapor-lock, it wasn't - it was a bad
reference sensor. </FONT></DIV></BODY></HTML>
