weber spacer query
I am sure this has been asked, but I can't find it.
How important is the thick "phenolic" spacer between carb and manifold, what are the pitfalls of leaving it out?

It's probably to isolate the carb from the engine heat. Without it the fuel in the carb may boil / evaporate
I'm addicted to brake fluid, but I can stop anytime.

The spacer is to limit the carburetor vibrating with the engine. The carb should be able to move slightly, relative to the engine / manifold. I would
recommend installing the spacer as it made a difference on my car.

Not sure how it limits vibration 
It's to prevent fuel vaporisation in the carb through heat transfer. It's also probably part of the inlet tract length design?

You are thinking of Misab plates, or similar systems with large O-rings. I suspect the OP is talking about a solid phenolic spacer which is used for
heat isolation and I also suspect he may be talking about a downdraught carb as I've never seen phenolic spacers used with DCOEs.

clearence would certainly be better without the spacer under the downdraught carb. Not sure what it's there for, always assumed it was to limit
heat transfer so never tried removing it.

Ran mine without one for years without apparent problems, to increase bonnet clearance.
Phoned the local ramblers club today, but the bloke who answered just
went on and on.
