RE: Gulp Valve

[WJAD81D@prodigy.com (MR JOHN P ELWOOD)]

To paraphrase, someoen wrote: "What does a gulp valve do?"  A gulp 
valve, as far as I know, is only needed on MGBs with an air pump.  
The air pump alone causes backfiring, and the gulp valve somehow 
prevents it.  It you have an air pump, and your gulp valve goes, you 
might start getting some backfiring.  The only replacements availible 
now are stamped "Nissan" or "Datsun" and don't look right.  You can 
find NOS, but the price will make you go... glup!
