<VV> Vapor Lock

[J R Read_HML]

On the OTHER hand...

I've driven a Vair out there (a 140) - from IL - without changing ANYTHING - 
carburetion, timing, anything.. and never had a problem.  Just noticed it 
being slightly less peppy on long uphill climbs - but was still passing most 
everything else.  Did NOT run into VL and NEVER have on a Vair.  I average 
12 to 15,000 MPY (miles per year) on the "fleet".  Oh, the entire fleet has 
mechanical pumps.
