Hi, Tyson,
Assuming it's an SU, or even any carb with a similar float chamber lid
arrangement, there is one possible fix.
Since carb alloy is soft, the threaded holes for the fixing screws can
get pulled up, esp. if overtightened. The lid then sits on the raised
burr and can't compress the gasket.
Take off the lid and using a large drill bit of countersink bit,
carefully ream away the edges of the holes.
If you do need to use a sealent (shouldn't be necessary) use a minimal
amount of blue Hylomar or equivalent. Also, have you checked that the
overflow pipe isn't blocked-that would build up pressure in the float
chamber. IMHO, if one carb is holding fuel and the other's leaking,
excesive pressure is not likely to be the cause.
Re. your silencer (muffler) the angle of the tailpipe should make much
difference. You probably
have a silencer-or even two-with baffles. On my B, both silencers are
absorption type (straight through) and
the car really bellows. The only way to tell for sure is to take off the
silencers and examine them. If you can't see right through, the silencer
has baffles.
When I first got my car, it was too loud, so I replaced the centre
Cherry Bomb with a cylindrical silencer. You could try mixing and
matching silencers or, if the rear one has baffles, running without the
centre one. Remember that a less restrictive exhaust needs a richer
mixture.
Hope this helps,
Dave Hill
