thanks guys
is it very hard to install the exernal pulse line to the carb? or is it jsut a matter of drilling and tapping in a brass fitting?
so i can make the intake manufold out of any matirial so long as it is the same length and is heat proof?
the reason being is that i can't get hold of large diameter aluminium exept for the bit that dad wants to use to make a piston[&:]
so could a large piece of brass, or a heatproof plastic suffice?
