Press fit forces of cozycarb

The measured diameter of the carburettor output couplings are 43.22mm

The measured diameters of the cozycarb heat block input coupling are 43.09mm

Both dimensions measured with two separate calipers (using internal and external jaws), agreeing to within 0.01mm

This total interference of 0.13mm would be expected to translate to an excessive press force, surely crushing the carburettor
