[TR] SU carb fuel bowl

[Bud Rolofson]

Not a joke just an incomplete statement.  I should have said ZS carbs  
don't have a designed float chamber vent that ends up with liquid gas  
dripping directly onto the exhaust the way that SU carbs apparently do.

Since the thread was venting liquid gas onto the exhaust I was  
thinking that a ZS carb doesn't vent liquid gas onto the exhaust  
directly.  But I didn't really write that. They will leak liquid gas  
if the float valves stick but it comes out in unpredictable places not  
a tube like the SU carbs.

I know from experience ZS carbs vent emission gas fumes because I had  
some 74 carbs that wouldn't run very well unless all the hoses were  
used.  Glad I switched to 71 carbs that had less venting going on and  
less hoses to deal with.

Sorry for the lazy writing.
