<P>Hello</P>
<P>David is 100% correct. I have worked on 100s of Corvairs and never seen a vapor lock. I would suspect the coil.</P>

<DIV><FONT face=Arial size=2>Sometimes these problems can be daunting especially when they are intermittent.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There is another possibility, I mentioned that vapor lock was unlikely but I assume the insulator blocks are in place under the carbs. You might want to check just to be sure sometimes people use the little gaskets instead! You should be able to see them under the carsb with a small mirror. They are about 3/16ths of an inch think and are hard plastic/fber. </FONT></DIV>

<DIV>Thanks David. We did look down the carbs and no gas was squirted.</DIV>
<DIV> </DIV>
<DIV>The first time this happen it was a very hot day. I had shut off the car and my wife and I went in for lunch. When we come out it would not start. I removed the entire breather assembly and let it cool down. The I had my wife try to start it while I tinkered with the cokes.</DIV>
<DIV>Chuck Leonard suggested the fuel pump also. My plan is to check the pressure.</DIV>

<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></BLOCKQUOTE>
