MG MGB Technical - HIF4 Question

Hi,
I've just found that the K&N air filters fitted to my HIFU SUs, seem to have been fitted upside down!
Where the air filter, stub stack and gasket, fit to the carb, there are 2 holes (in addition to the mounting holes) in each that line up with 2 holes in the carb. But with mine being 180 degrees out the holes in the carb were blocked.

Does anyone know what these holes in carb are actually for. And what effect blocking them would have?

Thanks in adavance.

Charlie.

Having found that, just reinstall them the correct way round and go merrily on your way :o)

However if the carbs were setup with them blocked it may be advisable to set them up again from first principles.
