Stormy,
Good timing on this subject.
Last years condition inspection on Larry's RV-6 (450tt)we did some
reinforcing fiberglass layups on the bottom of the FAB, where the K&N filter
rubber ridges were wearing thru the bottom.
Right now, I'm doing the condition inspection on My RV-6 (500tt) and found
the same thing.
No problems with the Carb.......but will be looking closer Saturday now Smile
Thanks for the update.
Bob Martin--o-360 C/s larry's is 0-360 with f/p neither one
balanced yet! but soon.

Checking some incidental things after the fuel tank SB was done (unusable
fuel quantity and flow rates from each tank) I discovered how much havoc
the engine vibes have been wreaking on FWF stuff since my last good look in
there. The carb heat flapper in the FAB has broken a hinge eyelet, the
hinge has cracked away from one side of the FAB fiberglass sidewall, the
flap itself, which used to lie flush inside a slightly smaller hot air
intake hole, has fretted its way all the way through the aluminum FAB top
so that in the full-open position it actually leaks induction air out the
top of the FAB. Most distressing to me was the realization that the
vibration-motion of the FAB against the lower cowl intake scoop had caused
the carb halves to fret and loosen considerably on their gasket, even
though the 4 screws holding the upper and lower carb halves remain firmly
safetied in their original positions. The FAB and lower carb body to which
it is bolted can be rocked easily left-
to-right with trivial pressure on the air inlet portion of the FAB.

I had noted the abrupt appearance of gel-coat cracks in the cowling around
all the front openings since my prop was balanced 2 years ago, and now
this... The prop and engine are much smoother-running than ever, but
fatigue/wear seems to be escalating. Probably a coincidental observation
on an airframe that is starting to show its 580 hours, but curious just the
same. Maybe I can blame this on the P-mags Wink ...not.

I'm curious whether anyone else has experienced this thing with their carb
and FAB gradually coming apart in pieces.
