[Tigers] Fuel Pressure

[csx2282]

Leaky brass floats aren't the only ones that can cause problems.  Composite 
floats can too.  I once had a Dodge equipped with a Holley with a side 
mounted float.  After several years it started having a problem with 
stalling while turning, but only in one direction.  After asking around, I 
found out that this was a common problem with this carb.  It turns out that 
composite floats tend to lose their bouncy with age.  Since the float was 
side mounted, there was a stronger centrifugal effect on it in one direction 
than the other, resulted in fuel starvation.  With cross mounted floats, 
this can cause stalling during hard braking.

Whenever I do a carb rebuild, I also replace the float(s).  I suppose you 
could have brass floats checked for leakage, but I've never bothered.  With 
composite floats, replacement is just a given as far as I'm concerned.
