[TR] Smells and wives

[Kinderlehrer]

I think I started the discussion with a question about losing gas through 
the overflow. I think I solved that problem with Randal's suggestion to 
remove the overflow and vent the gas cap. Worked fine on this morning's run 
but no long trips yet.  Most of the times I have had gas smells in the 
garage, however, were from leaks from various places in the carbs. 
Complaints went down after rebuilding them.
