The spitting seems to be cured by fitting fine gauzes (40 strands per inch one, each side of the upper transfer port gasket) and using no.3 slide cutaway, needle position 4 (second from weakest) and 190 main jet to take account of the ethanol. Any comments appreciated.
In passing, is anyone know an expert on Amal 276 carbs, the various types – I suppose different models had different pilot jet sizes – which is correct for the 2-speed Scotts?
